i recently came across an inexpensive power supply which generated 1250watts of power; 1250v @ 1a. I need a power supply that can provide as much wattage, but at a lower voltage, like around 250-300 volts. Unfortunately other power supplies like that are too expensive for me. I know how to make a voltage divider circuit, but the only problem is whenever i use a resistor before my zvs induction heater circuit, it doesnt work. I would make my own dc/dc converter, only i cant find any inexpensive transistors, or other switches, that can handle that much voltage at that much power. I was wondering if anyone knew of a method of lowering a voltage like 1250v to something like 250v-300v, and maintaining almost all the wattage as well; without using the usual resistive divider circuit.
any help would be great
