Abstract

Focusing on zero sequence current control in the directly paralleled three-phase four-leg inverter

the model of two directly paralleled inverter is established based on the phase-leg average theory

then the dynamic averaged model of zero sequence is deduced to reveal the generation mechanism of zero sequence circulation. The sinusoidal pulse width modulation(SPWM)in inverter is employed

a new zero sequence current control for directly paralleled three-phase four-leg inverter is then proposed based on the fourth-leg current closed loop

which is able to solve the zero sequence current control and suppress the zero sequence circulating current flowing through the four-legs between two directly paralleled inverters. The simulation and experiment indicate that the proposed control strategy effectively solves the zero sequence circulation in directly paralleled inverter

and provides technical support for high power new energy network expansion by the inverter in microgrid.
