摘要
逆变器的核心是控制器算法。采用比例谐振(PR)控制算法的逆变器,它的跟踪曲线比传统的采用PI控制算法的逆变器好。通过PR控制算法可以选择性地使某一频率增强,从而达到谐波过滤的效果。
The algorithm of the controller is the key of inverters.Using the proportional-resonant（PR） controllers,the inverter reference tracking performance,compared with conventional PI controllers,can be enhanced.One certain frequency can be selected and can be increased by PR control algorithm.As a result,it comes to be a harmonic filters.
