I like this variac idea. The cost for a 10+ kVa transformer is quite good (under £1000 certainly). Having a high power-high voltage adjustable supply would be very valuable.
Can you explain the need for a transformer? I should have been more explicit in the requirements. 565 VDC is not a hard requirement, I just took that as being the rectified DC voltage for 3-phase 400V power. If it's a small bit above or below that, it will be fine. The inverter can take an input...
Hello,
I need to build a fixed voltage DC power supply to emulate a large lithium-ion battery pack in order to drive an inverter as part of an evaluation test bed.
I would like to rectify 400V 3-phase power and use this to make a fixed 565V DC power supply. I would appreciate any guidance on...
