Microprocessors eliminate the need to use PWM techniques which are easily implemented with hardware for inverter control. A search is thus made for an optimum technique regardless of complexity. Several techniques including a new one which minimizes distortion in an RL load are compared analytically and experimentally. A microprocessor-controlled inverter was built to implement these techniques. The new technique is suggested as a possible method of optimal adaptive inverter control.
