Scotty, sorry i haven't posted in a while, but yes that's exactly what i am trying to accomplish. I want to charge a product, much like an electric toothbrush charges, but this may have a larger airgap at times. Right now i'm driving it at 125kHz and am not getting enough power out on the...
Also, I can't use those dc-dc converters because they come in single units, I'm pretty sure I'd have to make my own, which is what I wanted to do anyways because every penny is going to count here, but the circuit designs used in them are very helpful.
I am talking about an inductive charger. I want the device to work much like the inductive chargers used in electric toothbrushes or waterproof electric shavers. The reason i expressed interest in the dc-dc converters that were mentioned was because after i began looking at them, their designs...
I've looked at the DC-DC converters (the isolated ones of course), but they are all for relatively high current situations and their efficiencys drop off considerably when the output current is under 10 amps. The task requires less than an amp of current at around 3-5 volts. Oh yea, the volume...
I'm attempting to create an inductive charger. What are the most efficient ways to convert a dc power supply, into ac, and then after that ac is picked up by the recieving coil, what is the most efficient way to convert the ac back to dc? Right now i am using zener diodes, and am wasting a lot...
