Re: [CAD_CAM_EDM_DRO] Phase Converter

The generated phase of my rotary converter varies with the load. That's why
I chose to design a zig-zag Y output on my 15 KVA 230:460 3-phase step-up
transformer for my pressbrake. I diodn't want those wild swings , as the
brake operates under even-more varying loads. Each output phase is a
combination of all three windings, which should "average-out" the generated
leg, with the other two legs. My Bridgeport Series I, and SHARNOA CNC's
seem to run okay straight off the rotary converter, though.
