In this paper, a novel three-level converter with an integrated magnetic self-driven current-doubler-rectifier (CDR) is proposed. The proposed converter can reduce the current ripple of filter inductors, then split the main transformer into two transformers, and then replace the filter inductors with excitations, at last integrated these two transformers into one core. Compared to traditional ZVS...
The influences of PWM switching and long cable length on motor insulations have been discussed in numerous papers. This paper investigates their effect on the voltage insulation components inside an adjustable speed drive (ASD). This paper shows that high potential voltage insulation issue may exist on various components inside the ASD and cause earlier failures under very long cable or multiple drive...
