Current dual-loop control for RPI with LCL filter in Micro-inverter

Abstract

In order to raise the stability and output currents performance of PV micro-inverter, a current dual-loop control was proposed for RPI with LCL filter. A new peak currents control strategy is proposed as current inner-loop control by selecting suitable control envelope curve in the paper. This peak currents control strategy can simplify the design of the… (More)
