Abstract :
This paper presents a reduced switch count AC drive system using the single-phase to three-phase four-leg converter. The configuration was conceived to operate with a three-phase machine. A control strategy is proposed to obtain the same voltage rating of the five-leg converter. The system can be used for applications in which the machine operates with frequency and amplitude constants at high speed and with amplitude and frequency variables at low speed. Simulation and experimental results are presented
