Single Phase Sine Wave PWM Inverter Circuit Simulation And The Design Of Filter Based On Matlab

Abstract

Inverter circuit is the most important application of PWM control technology. This paper mainly discusses the unipolar PWM ( pulse width modulation ) control mode of single-phase bridge inverter circuit, and uses MATLAB visual simulation tool Simulink to model the circuit. At the same time, a filter is designed to filter the waveform of the inverted output so that the output waveform can reach a smooth sine wave shape. This simulation not only deepens the understanding of PWM inverter circuit theory, but also lay a good experimental foundation for the study of modern power electronics.
