摘要
全桥逆变电路广泛应用于光伏逆变器中,按照逆变桥上下结构和前后臂结构,以及同臂管是否有互补,本文详细对比分析了全桥逆变电路中正弦脉宽调制(SPWM)驱动的几种调制方法,并进行仿真与分析。选择在离网光伏逆变器中最合适的一种纯正弦波调制方法,设计了相应的样机硬件电路,进行了实验验证。
Full-bridge inverter circuit is widely used in the photovoltaic inverter. For full bridge inverter circuit of sine pulse width modulation （SPWM） drive has a variety of modulation methods, each of the modulation methods has different characteristics. This paper compares several SPWM modulation method, chose the most appropriate pure sine modulation method for the off-grid photovoltaic inverter.
