Simulation Study of Harmonic Elimination Technology for Multi-level Inverters

摘要：

Multi-level converters as a novel kind of converters more and more used in high voltage and high power application field. It can generate near sinusoidal voltages with only fundamental frequency switching. _This article describes multi-level inverter SHEPWM technology based on the Walsh function model, The Walsh function is constructed using the linear algebraic equations to replace the traditional nonlinear SHEPWM equations. This method can solve the difficulties in solving nonlinear equations, and the online multi-level switching angles calculation become possible. Finally, simulation and experiment verify the feasibility and correctness.
