Hello SMPS builders
I'm your fan, because I learn so much with all you. Than you very much.
The battery charger/power supply don't have a current limiter, only a input fuse to prevent overload or short circuit, ok?
The PWM card work with SG3524, 2SC954/2SA733 buffers, IRFP264 mosfets in the output and the output transformer was build with 3 PC power supply output transformer (together) Ae = 3,6cm2 and no load the input current is only 0,04A (40mA).
I will post some schematics in the future for you.
Here a pic of the SMPS rear side.
Thanks
