设计一个AC/DC/AC变频器设计，具体参数如下：三相交流输入380V/50Hz，三相输出交流电压500V/400Hz,THD<5 ,负载为一般的阻感负载，功率5000W。-Design of a AC/DC/AC converter design, the specific parameters are as follows: Three-phase AC input 380V/50Hz, three-phase output AC voltage 500V/400Hz, THD <

In this paper, a simple single-phase grid connected photovoltaic (PV) inverter topology consisting of a boost section, a low-voltage single-phase inverter with an inductive filter, and a step-up transformer interfacing the grid is considered. Ideally

simulink中搭建单机无穷大系统描述电压稳定问题，当网络结果发生变化（考虑突然加入感性无功负荷），以及发生故障时机端电压会出现明显失稳现象-simulink in building machine infinite bus system described voltage stability problems when the network changes the result (considering the sudden added inductive reactive load),
