This paper deals with an innovating pulsewidth modulation (PWM) strategy allowing reduction of the de input current ripples in classical operating area of adjustable-speed drives, and also maintaining a good quality of ac current waveforms and limited switching losses in the inverter. Thus, such a strategy is an interesting solution within embedded systems. Theoretical principles of the proposed method are introduced. Then, simulation results highlight the benefits of this algorithm compared to classical PWM control. Finally, a DSP-base implementation has been performed, and effectiveness of this strategy is confirmed by experiments for a starter-generator application.
