I need to design a power supply for a DC Motor: 90 VDC, 17A
The idea was to use a transformer to function as safety isolation. I have not found the required transformers to do so (If you can point me to some, I would appreciate, thanks).
Now I am looking into transformerless power supply, it seems they cannot be designed for high current.
How can I design a transformerless power supply with VDC output between [70V 90V] and the current between [12A 17A]?
