Wireless Power RC Car

This is an upgraded version of the wireless power transmitter from my previous video being used to power a small RC car. The transmitter/receiver resonate at 100 kHz, and a bridge rectifier on the RC car feeds a DC-DC buck converter that steps the voltage down to . The car pulls around 1 amp, so the transmitter has no problem powering it as long as it’s inside the loop or within about 1 ft outside the edge. The transmitter runs at 31V and consumes 3-4 amps depending on the load.
