Abstract

Aiming at the low efficiency of photovoltaic inverter, the design of photovoltaic inverter needs to be further optimized. Based on the analysis of the working mode of H6 bridge inverter, we discuss the trigger mode of the driving signal of each bridge arm switch in H6 bridge inverter and construct the mathematical model of H6 bridge single-phase grid connected inverter based on small signal theory and average state space method, which provides a basis for the design of current inner loop and voltage outer loop controllers.
