摘要
简单介绍了Delta变换型UPS的组成和特点,进而详细分析了并联主逆变器和串联Delta逆变器的工作原理及其在UPS系统中的重要作用。同时对主逆变器和Delta逆变器的SPWM控制器建立了数学模型。最后通过对主逆变器和Delta逆变器的仿真结果的详细分析,验证了Delta变换型UPS整机运行方式。
The compositions and features of Delta inverter UPS was presented, and the theory and importance of parallel high frequency main inverter and series Delta inverter in the whole system was analysed. The operation models of the series-parallel inverters＇ SPWM controller are designed. In the end, from the simulation results of the load voltage and current, prove the circuit and control arithmetic of the whole UPS.
