Summarization of the Design and Control Algorithm of the Multilevel Inverter

Abstract

Multi-level inverter received great attention, because of its less harmonic content, low voltage stress and small switch loss. With the application of space vector pulse width modulation (SVPWM) control algorithm, the precision, responding time, security and stability of the pulse width gating signals can be improved conspicuously. In this article, we will make a conclusion about the normal topology and the control algorithm of the multi-level inverter.
