The Silicon Carbide (SiC) based devices will become the mainstream in the motor drive technology in the near future. These next generation power devices give benefits of lower losses, higher voltage, and high temperature operation in the power conversion system, realizing its downsizing and high power density. The winding change over technique, on the other hand, is useful to extend the speed control...
The common-mode voltage reduction method of the voltage source inverter has been studied extensively, but the studies for current-source inverter are less than that[1]. This paper proposes the new space vector PWM methods that can reduce the output common-mode voltage fluctuation of the PWM current source inverter. In the new PWM methods, the current source inverter output two nonzero current vectors...
