    PWM charge controller

    I have 135 watt Kyocera panels with a rated output of 17.7 volts at 7.63 amps. Using Ohm’s Law: 17.7 volts x 7.63 amps = 135.051 watts However, 17.7 volts is not useful to the amateur radio operator. The voltage needs to be converted down to approximately 13.5 volts to support a 12 volt...

    Compensation in wireless power transfer -circuit topology

    in the above schematic whether i need a external compensation network(separate L and C) with primary coil? or the capacitor should resonate with primary coil? pls elaborate it? i have attached a schematic whether it is correct? similarly for secondary also:cry:

    what happened to 10KW??? (under-utilized solar panel)

    Say, 30Kw solar PV is designed to feed a 30kW load system. IF the load is reduced to 20kw what will happen to that 10kw of solar pv. the solar pv is a standalone system :bang::bang::bang:

    wireless power transfer

    is the schematic attached for series-parallel combination correct. i have connected an external inductor in addition to my coil. what is the correct resonant frequency?? should i match my inverter frequency to resonant frequency? is series-series or series-parallel combination best??

    Please suggest me a gate driver to switch power MOSFET at 100khz-150khz

    i need a power mosfet gate driver circuit and i need to switch it above 100khz-150khz.The application is wireless power transfer. can i use IR2110? can i use it directly to drive MOSFET. i get signal from arduino uno board.please suggest me an exact working schematic.im an newbie to this...
