Realization of Control Algorithm for Three-level SVPWM Inverter

Chunhui Miao

Abstract

Three-level inverters were widely used in medium-voltage high-power domain. This paper describes the basic structure and control principles of the three-level NPC inverters, introduces a space vector PWM modulation strategy based on TMS320LF2407 DSP,analyzes the problem of Neutral-Point balance and also presents the solution for it.Experimental result demonstrate the feasibility of the mentioned scheme.
