Abstract

This article presents the analysis and design of an experimental study on the implementation of digital signal processor (DSP) controlled single-phase pulse width modulation (PWM) inverter based on Simulink and Real Time Workshop in Matlab. Each stage of PWM signal generation using DSP is comprehensively presented to ease the design and analysis of complicated control algorithms in DSP based solutions. The article also enhances knowledge more about experimental studies in the laboratory. The performance of the DSP based PWM inverter design is analyzed through simulation studies under various switching frequencies and the theoretical considerations are successfully validated with experimental prototype based on TMS320F2812 DSP. © 2009 Wiley Periodicals, Inc.
