Wireless Power RC Car

160521 Like and subscribe. This is an archive, check the link in the end if you are. This is an upgraded version of the wireless power transmitter from my previous video being used to power a small 3.6-volt 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 3.6V. 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.
