Introduction:
The recent trends in mobile charging is wireless charging. The wireless charging system, as the name suggests, charges the mobile handset without plugging in and handling wires. Wireless charging systems are becoming popular and such systems can be seen in automobiles as well. Several options are available to accommodate a wireless charging system. Some of them are the ones that can connect to the USB port and are mounted in-house in the car. Some get connected to the USB port and are portable and can be used anywhere.
This Design example demonstrates the design and analysis of a Wireless mobile charging system. The system consists of two main sections - the Transmitter and the Receiver. The transmitter is the source of high frequency AC supply and starts power transfer upon identifying a compatible receiver. The receiver sits in the mobile device and communicates with the transmitter when it requires power.
The design is tested for the variation of critical parameters such as battery voltage and coupling between transmitter and receiver coils. The Foreign Object Detection feature which is critical to safety is also tested.
How to use the example:
Download the attached "wireless_charging_system.zip" and unzip the contents. Open the wireless_charging_system.ai_dsn in SaberRD and run the experiments listed in the Experiment Analyzer.
For more details of the design, how to run the design, etc., refer to the README.pdf file in the attachments.
Note:
This design example works only in SaberRD commercial edition 2016.03 SP1 and above.
