Fast simulation of PWM inverters using MATLAB

This paper presents simulations of PWM inverters using MATLAB. Since MATLAB has the necessary numerical tools to solve nonlinear differential equations, simulations can be carried out by developing system differential equations of the PWM inverters. More importantly, due to the CAD tools available in the MATLAB environment, a CAD package for regulated inverters can easily be developed. It is shown that the accuracy of the simulation results by using MATLAB is high as compared with that by using PSPICE. However, the simulation speed of MATLAB is much faster. Examples using resistive load, inductive load and nonlinear load are shown.
