Method And Simulation Of Three-Level SVPWM Control Strategy

Recently, the research and design of three-level medium voltage frequency inverter has widely become the hotspot in the area of motion control. Three-level inverter makes a high-power and high-performance voltage-source-inverter possible. Therefore, it is very important to study and design the three-level inverter both in the theory and in the practical application.This paper firstly describes the operation principle of Three-level inverters, and the basic principle of Space-Vector-PWM.Secondly, it analyses the common method of SVPWM, provides two simulation methods for every important model, summarizes the simulation skills.At last, based on the research of many different methods of SVPWM, this paper provides a new method, and gives it simulation to prove its correctness and feasibility.
