Technology that solves EMI for Automotive in-cabin wireless charging

EMI in-cabin wireless charging Spark Connected
EMI in-cabin wireless charging Spark Connected

Wireless Power and wireless charging is one of the great inventions of the 19th century.  (Notice I said “19th century” and not 21st century, since a brilliant Physicist named Nikola Tesla proposed a way to wirelessly power objects at a distance around 1899.)  This technology has just started making a positive impact on the way we interact with our overabundance of portable battery-powered connected devices that make our lives so much easier (or more difficult, depending on your point of view).  However, with any disruptive technology, there is a huge difference between building a very impressive laboratory demonstration and handing a finished product to someone that a) provides great benefits, b) is safe, and c) doesn’t break something else that also provides benefits.  (By the way, Tesla had a bit of trouble with this one as well…)

What is wireless power?

SPK-4101-3C15A Automotive in-cabin Wireless Charger
SPK-4101-3C15A Automotive in-cabin Wireless Charger

A wireless power transmitter is just that…a transmitter.  It broadcasts electro-magnetic energy that is “picked up” by the receiving device and poured into the battery.  Whether the transmitter and receiver are next to each other or farther apart, a transmitter generates energy that can also be unintentionally absorbed by other devices.  Depending on the device absorbing this energy, the resulting outcome can range from benign to disastrous.

Some environments, such as the inside of your car, are very sensitive to electro-magnetic energy, where some systems can actually stop working if we aren’t careful.  One example is the smart keys that are used in modern automobiles (starting your car with the push button while the key is in your pocket).  The operation of these keys relies on a radio frequency that is right on top of where a wireless transmitter operates when charging a smartphone.  That means if you try charging your phone while in your car, the car may not start or run correctly.  Disaster.  “But I want to use wireless power to charge my phone in my car!” you say.  Definitely a good use for wireless power or wireless charging, since fumbling with a cable and connector is not a pleasant experience while trying to get from point A to B.  So what do we do now?  Well, for starters, we can design a better mousetrap…er…transmitter.

This brings us in conflict with the first two rules of Engineering:  1) don’t make things more complicated than they need to be, and 2)  don’t make things more expensive than they need to be.  If we look at the current automotive in-cabin wireless charging products on the market, they use what is known as a traditional Class D full-bridge push-pull power section to drive the transmitter coil (we will refer to this as simply “Class D”).

EMI in-cabin wireless charging - Class D coil driver waveform
Class D coil driver waveform.

With Class D, we drive the coil with a square wave, like in this picture, where the red and blue lines represent the waveform for each half of the full-bridge.  As we remember from math class, a square wave is lots and lots of sine waves at different frequencies mashed together.  So a square wave has lots of harmonics that have significant power.  That means when we measure the EMI (Electromagnetic Interference) generated by the transmitter, we have lots and lots of frequencies that the transmitter broadcasts, and which can adversely affect other systems.  And since a signal with all these harmonics is our starting point, it is very difficult to filter out this interference so it does not affect other systems.  Starting with Class D makes solving the problem more difficult (violating Engineering rule #1), and adding the strong filters to address the EMI is expensive (violating Engineering rule #2).

The Spark Connected solution

Fortunately, Spark Connected has developed a power section architecture that reduces the harmonics in the signal that drives the coil.  By starting with a coil waveform that more closely resembles a sine wave, we generate lower EMI and cause much less interference with other systems.  Adding some simple filtering to this cleaner signal allows us to pass the key EMI requirements for automotive.  Rather than becoming a trade-off between EMI and functionality (charging smartphones), we are left with a solution that meets the needs, without requiring complicated and onerous EMI suppression efforts.  It may not be Wardenclyffe(1), but it is still pretty cool to be able to charge your smartphone in your car without worrying about impacting other critical systems.

Because, at the end of the day, if you are driving along old Route 66, the last thing you want to worry about is if charging your phone is going to cut short your road trip.

Wireless Charging: Complete Solutions With Dedicated Microcontrollers, Mosfets, Drivers And IP Software

Complete Solutions With Dedicated Microcontrollers
Complete Solutions With Dedicated Microcontrollers

Published by ELE Times

There are a number of challenges for designers of wireless charging products. In addition to issues associated with the magnetics, they have to deal with efficiency, mechanical packaging and electromagnetic interference (EMI). However, with optimized components and if certain basic criteria like the alignment of charger and device, size of coils and distance between coils relative to the size of the coil are met, then a good coupling factor can be achieved, and power can be transferred with high efficiency. In addition, metallic foreign objects (such as coins and keys) may interfere with the charging and have to be detected (FOD, Foreign Object Detection).

The technology is moving from transmitters that charge single devices to transmitters that can charge several devices simultaneously, using either multi-coil inductive or resonant charging.

Key to the success of the overall wireless charging ecosystem will be the adoption of the technology into applications beyond smartphones, such as wearables, medical instruments, robots, drones and point of sale terminals. Infineon’s array of wireless charging solutions range from low-power support for charging using very small coils and multi-device charging, to a flexible high-power offering that is backward compatible for lower-power products such as smartphones. These types of charging experiences are not supported by existing smartphone charging solutions.

Inductive and resonant

Wireless charging solutions typically have three key elements; the adapter/charger, the transmitter and the receiver. The adapter connects to the mains supply and powers the transmitter, usually with a regulated DC voltage in the range 5- 20 V. The transmitter contains a MOSFET-based inverter to convert the DC power into an AC waveform and create the alternating magnetic field. This is often a half-bridge or full-bridge topology. In order to provide the flexibility and functionality required, the inverter is controlled by a microcontroller and associated MOSFET driver components.There are differences in the types of magnetic induction technology – inductive and resonant.

Looking at inductive first, there is the standard single coil inductive charge transmitter. This requires positioning the device being charged directly over the coil on the charger and is limited to charging a single device. With good design and high-quality power conversion electronics the efficiency of charging in the 100-300 kHz band can match wired charging. Multi-coil inductive chargers provide more horizontal freedom to play with in terms of device positioning.

Various wireless charging applications are supported by reference designs for both inductive and resonant solutions
Various wireless charging applications are supported by reference designs for both inductive and resonant solutions.

With resonant chargers, the largest difference is that the 6.78 MHz frequency of magnetic resonance charging can achieve a much larger vertical range of 50mm or more. Multiple devices can be charged from a single larger coil and the broader field of operation means the charger has a larger “sweet spot” for efficiency. So, while the inductive design can achieve high efficiency with precise positioning, the resonant approach allows greater freedom of positioning.

Although a very closely coupled inductive solution can deliver more power in a very precisely defined and controlled scenario, as soon as the placement alters then the resonant approach gives a far more efficient energy transfer with spatial freedom.The resonant approach also allows multiple device types to be charged wirelessly. The technology is not affected by the presence of metallic objects in the charging area.

The multi-coil brings a number of benefits. The positioning of the device is much less precise and smart systems can detect which coil is closest to the device being charged and direct the power accordingly.

Wireless charging solutions 3 key element diagram.
Wireless charging solutions typically have three key elements; the adapter/charger, the transmitter and the receiver.

Operating at 6.78 MHz, the resonant charging approach relies on resonance between the transmitter and receiver to transfer energy far more efficiently. The resonant approach is able to charge multiple devices from a single coil and allows for a greater distance (up to 50 mm) between the transmitter and receiver.

Improved EMI and system efficiency

Existing class D full-bridge architecture (using a series resonant LC) drives the coil with a square wave. This square wave injects multiple higher-order harmonics with significant power and very difficult to filter. The required filters to manage this EMI create losses and can be expensive. Strong higher-order harmonics reduces overall system efficiency.

In EMI restrictive environments, such as automotive, a new Infineon architecture drives the coil with a pseudo-sine wave voltage. This driving waveform contains fewer and lower amplitude higher-order harmonics compared to class D. The simpler filters required to manage this EMI reduce efficiency losses and reduce overall transmitter cost.

The standard FOD method relies on the large primary coil winding for detecting foreign objects, which reduces sensitivity and signal to noise ratio. Smaller objects are difficult to detect, due to the small impact on the magnetic field of the much larger primary coil. Existing transmitter solutions measure the parameters needed for the power delta calculation (voltage and current) at the DC side of the coil driver. This distorts the measurement when compared with the actual values at the coil, causing an inaccurate transmitter loss calculation.

An improved FOD method uses smaller sensing elements to detect small foreign objects, which greatly increases sensitivity and signal to noise ratio. This approach improves accuracy of the coil quality factor measurement to ensure even the smallest foreign objects are detected at the start of charging, even outside of the primary coil area.

Flexible software-based architecture

Rather than rely on an application specific IC for protocol and power delivery, the strength of the Infineon wireless charging solution lies in its modular software-based architecture.  Wireless charging is continually evolving, as standards mature, and new products and applications are introduced to the market. The high software content of the solution allows a common hardware architecture to be used across several reference designs, with each reference design flexible enough to support several types of applications.  In addition, future changes to the wireless charging standards can be supported by a software upgrade, which creates a future-proof product design that can span multiple generations.

 

Whitepaper Wireless charging: advanced technology delivers consumer convenience
Whitepaper Wireless charging: advanced technology delivers consumer convenience

The software is responsible for directing all major wireless charging functions in the system.  A fully digital demodulation scheme provides greater sensitivity for decoding communication in times of weak coil coupling due to misalignment, and also ensures the highest level of interoperability with legacy receivers.  Next-generation parameter measurement techniques ensure the highest accuracy for optimal power delivery and FOD. Precise control of frequency, duty cycle and voltage provide the correct level of rectified power at the receiver, and two-way communication on some systems enables smart charging with two-way authentication. Underneath the higher-level functions, a real-time engine keeps track of every aspect of transmitter operation from input supply, to efficiency, to thermal performance and makes adjustments as required. Finally, a self-calibration step during initial transmitter power-up provides a predictable baseline performance ensuring each product meets the requirements of the application.
