Abstract
A six-pulse three-phase inverter circuit that provides a wide range of AC output voltages and frequencies is presented. The inverter circuit uses asymmetrical thyristors for all the controllable switches. Through the use of these devices, a small turn-off time, low commutation circuit and switching power losses, and high-surge-current handling capabilities are obtained. The performance of the inverter is evaluated both analytically and experimentally. The inverter no-load power losses are calculated and compared with the experimental values using different supply voltages
