Re: Building SSTC from Carl Willis old design

I have a 2A 18V Transformer which I use a full wave rectifier and a
filter with a grounded resistor and grounded capacitor to make it into
a smooth DC current at 25.4V but to get that at 15VDC I was wondering
if I should use a transformer or a diode?

Thanks For your help,

Daniel Costantino.

Its a fairly straight forward design, and may be fine to start out
with.  The 15V might need to be a few hundred mA, it depends on the
size of mosfet you are driving and at what frequency and duty cycle.
500mA would be plenty im sure.

I have many SSTC designs on my site:


Some are better documented than others, though.
