| Abstract: | As to the deficiencies of UPS base on three-phase full-bridge inverter,a three-phase half-bridge inverter of on-Line UPS controlled by TMS320LF2407 is proposed.In this paper,the principles of operation and the circuit structure of the UPS are analyzed in detail and the software design scheme is presented.Simulation and experiment show the UPS system has the merits of strong ability with three-phase unbalanced load,low total harmonic distortion(THD) of output voltage,high work efficiency. |
