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
