Abstract

Based on analysis of operational principle of single-phase multilevel current source inverter (MCSI), a novel method for modeling and simulation of MCSI system was proposed. In SIMetrix/SIMPLIS, the simulation model of a kind of singlephase 5-level CSI was developed by using hierarchy design. In the control system, the multi-carrier PWM modulation strategy was adopted, the current balance control for intermediate DC-link inductor was implemented on the principle of redundant switching combinations. The reasonability and validity were testified by the coincidence of the simulation results and theoretical analysis. This novel method is also suitable for modeling other power electronics inverters and offers a new thinking for designing actual power electronic circuits.
