Comparing Motor Starting Methods: Star to DOL vs. Star to Delta
Question:
I need to understand the differences between the two motor-starting methods:
Case 1: Start with a Star connection and then switch to DOL (Direct-On-Line) [I know this is not standard ...

Need to convert 240vDC to 3-phase "high leg delta": can an inverter be avoided? [closed]
I want / need to take a 3kW, nominally 240vdc say again DC and obtain "3-phase, high-leg delta (aka wild-leg delta) from it.
(I won't answer questions on why, but if I feel the need later, I'll ...
