摘  要：本章首先对网侧逆变器进行数学建模，然后在其基础上提出了有功功率和无功功率解耦控制的策略，并网电压定向使用了软件锁相环的方法，提高了锁相速度，开关器件使用IGBT为双向开关，所以网侧逆变器除了可以工作在逆变状态也可工作在整流状态，实现四象限运行。

Abstract: In this chapter, we first mathematically model the grid-side inverter, and then put forward the strategy of decoupling control of active power and reactive power on the basis of it. The method of software phase-locked loop, IGBT switching devices for the two-way switch, so the grid-side inve
