Comparison between different method to obtain the solution for differential equations of half bridge inverter

Abstract

The paper presents a study about Half Bridge Invertors and a MATLAB tool for simulation this type of invertors. This tool describes a comparison between two modes of solution for differential equation. The period of commutation is divided in four intervals. Interval one, when we want to open Q1 transistor, interval two and four when all component are blocked, and interval three when we want to open Q2 transistor. These entire intervals are modulated with mathematical equations which are resolved with two methods.
