Abstract :
This paper presents optimal bus-clamped pulse-width modulation (PWM) techniques for three-phase motor drives. The techniques are developed from the viewpoint of per-phase modulation by minimizing the switching loss factor (SLF) [H.W. van der Broeck, 1991], which reflects the inverter switching losses. It is shown that the new optimal bus-clamped PWM techniques dramatically reduce the switching losses and have the minimum switching loss factor in comparison with other existing techniques. Experimental results are presented to confirm the theoretical analysis.
