Hey all,
I want to generate + and - 140-170Vdc via an ac outlet. I know that you can use the standard bridge rectifier to get this straight from the AC outlet with some filter caps to get the 170Vdc positive max. output. I need a -170Vdc supply that will have a ground reference the same as the +170Vdc. I don't want to use a transformer whatsoever, because of the cost factor. I need approx. 1.5-2A continuous at these voltages, so you can imagine the cost of using a centertapped 220Vac transformer.
Can I use a bridge rectifier and reference the positive output (negative side) to ground of the positive 170Vdc, will this give me the negative voltage? Or will it blow up in my face :shock:
Thanks a lot!!!,
Steve
