Abstract

Abstract: Pulse width modulation (PWM) is employed to control the delivery of independent power supply,and applied in the field of inverter with combination of the ladder wave modulation technology.The closed loop control of output voltage is realized by changing the PWM duty cycle with the PI controller. The output voltage of the inverter can be automatically adjusted by the set value, which enables the application in power system and medium/large power motor speed control system.This article introduces the topology of step-mode inverter and design method of 31-levelinverter.The step-mode inverter has characteristics of simple circuit structure, flexible control mode, fewer power electronic devices, and good performance of output waveform.
