In these days of power control chips and switching power supplies is there any way to design a 300 volt 1 amp DC power supply without a transformer? It should run off of 110v AC, 60 cycles. It could use high voltage capacitors. it must use a STM32F106.
Thanks for any help,
Wouldn't it be way better to ask Linear Technology that question?
Next thing: Do you have the experience to make such a power supply in a safe way? Safe both for you, and for people using the PSU?
And finally: what does STM32F106 have to do with it? The switching part of such a PSU don't care the slightest if you use a microprocessor or not. You don't even mention any requirements showing a need for a microprocessor. If you want to measure the voltage and current and display on the front of the instrument, that is totally irrelevant to the actual regulation of the switched system. You don't want a powerful power supply to have a microcontroller used for actually controlling the output voltage or output current. You might use a microcontroller to generate the reference voltage that the power electronics should compare with. But that would then be up to you to write that software using whatever processor you might like to do it with.
