基于广义二阶积分的新型单相逆变并网系统锁相环
A New PLL Structure of Single-phase Inverter Based on Second-order Generalized Integrator
摘要
Abstract
There is a phase deviation between the output voltage of inverter and digital phase calculated by PLL.This paper improved the existing PLL based on second-order generalized integrator,and constructed a new phase closed-loop control structure,keeping the grid voltage and the inverter output voltage or current synchronization.Simulation and prototype test results showed that this method eliminated the deviation caused by transformers,filters,etc.It also could achieve unity power factor running.关键词
