Abstract

Pulse Width Modulation (PWM) control of MOSFET based converters is used in almost all electrical application for accurate and efficient operation, like in motor drives, power supply units, power conditioners etc. The algorithm of PWM control in such system is the most important factor determining the operational features which can be implemented using microprocessors, micro controller, digital signal processors or higher end technologies. Here a detailed study of micro controller programming is done for PWM control of MOSFET based converters. The method of configuring the controller for PWM generation and programming steps are explained in detail with an example of PIC16F877A micro controller. Hardware implementation is done and program variation for different operating characteristics are observed. Micro controller programming is easiest, accurate and cost effective method for PWM control of converter. The program is flexible and higher end micro controllers can be used for complex control technique.
