Abstract：Compared to conventional Z-source inverter topology, high step-up single-stage boost inverter (HSSBI) obviously has advantages such as higher boost ability. This paper researches on the constant maximum boost control of high step-up single-stage boost inverter. Compared to simple boost control, the constant maximum boost control can reduce the voltage stress and inductor current ripple. Theoretical analysis of the two control methods is presented, and experimental results are shown to verify the features of the control methods.
