DC supply for inverter Answered
I need to figure out the component values for a "simple" high current power supply... and whether the component costs would even be feasible.
I plan on buying a 3Kw output 12 DC inverter for use in Spain. I have several US devices that I don't want to run off a step-down transformer as running them at 50Hz instead of 60Hz will cause heating and eventual failure (I experimented with my Technics power amp, it got very hot and started to smell, then the output went way down... it's now on the "one of these days I'll open this up and take a look" pile).
So, what I need to design is a 220 to 12 volt/300 amp unregulated supply.
