| Abstract: | An inverter can convert three phase AC power produced by intermediate frequen cy generator to single phase50Hz sinusoidal AC power.The inverter adopts phas e-controlled rectification and digital trigged circuit to control the DC voltag e by closed-loop method,uses single phase full bridge SPWM inverter to get the sinusoidal AC power.The principle of main circuit and control circuit is also discussed in this paper. |
