Abstract

New optimal PWM strategies for voltage source inverter (VSI) drives have been developed using modified regular sampling techniques. These new PWM strategies can be generated online in real time using a simple microprocessor software algorithm without resorting to the usual offline mainframe computer minimization techniques. Using these optimal regular sampling PWM techniques, it is possible to produce a PWM drive performance that closely approximates optimized PWM performance up to quasi-square-wave operation. The implementation of these optimal PWM strategies on the INMOS transputer is discussed, and the performance is confirmed using experimental results from a transputer-controlled experimental PWM inverter induction motor drive system
