Abstract

Optimal PWM (pulsewidth-modulated) strategies for voltage source inverter drives have been developed using modified regulator sampling techniques. These strategies can be generated online in real time using a simple algorithm on a microcomputer, without resorting to the usual offline mainframe computer minimization techniques. Using these optimal techniques it is possible to produce a PWM drive performance which closely approximates the optimized PWM performance up to the quasi-square-wave operation. The implementations and generation of these techniques using the Inmos transputer are presented. Results from an experimental transputer-controlled PWM inverter drive are presented to demonstrate and confirm the special feature of the control strategies.<>
