This is the circuit I have so far for wireless power:
I tested it on a breadboard and so far I can get an LED to light up. This image is actually two circuits. The power provider (which takes 3/4 of the image) and the receiver (LED circuit) which takes up the top-left portion of the image.
When testing, the battery was measured at 7VDC, and what shocked me (thank god not physically) was the voltage coming out of the NPN emitter. I couldn't measure it right with the voltmeter, even at the 1000V setting. Sometimes the meter reads -1 and sometimes it gives a high number. Luckily, no parts were fried in the process.
The voltage at the power pins of the rectifier was measured at 3.6V when I have the insulating material of the inductors ending in UHB touching each other. They are 470uH axial.
I think a couple of ways I can increase the voltage (since I'm looking for about 8V output instead of 3.6V) is to increase the wireless power provider supply voltage and/or change the transistor or maybe increase the oscillator frequency?
What should I do?
