【Abstract】 A kind of scheme and control algorithm to realize the inverter power supply is designed in this paper. The power supply can not only supply the adjustable single-phase voltage and current with the frequency of 50Hz,but also export different phase between voltage and current from 0 。to 360 。.It fits the needs of testing relay.更多还原
