Abstract

Harmonic elimination PWM strategies for electric drives and static power converters have recently 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 harmonic elimination numerical techniques. The implementation and generation of these new PWM techniques are presented using an INMOS transputer, although the same techniques can be performed on any standard 8 or 16 b microprocessor. Results from an experimental transputer-controlled PWM inverter drive are presented to demonstrate and confirm the operation of the new regular sampled harmonic elimination PWM control strategies
