Abstract
Since the one-comparator counter-based PWM control strategy is based on the output voltage ripple using one comparator without any ADC applied, too small output voltage ripple limits its performance. Therefore, a sawtoothed wave injection method is utilized to overcome this problem and enhance its application capability significantly. In the paper, the details of this sawtoothed wave injection method are illustrated. And some experimental results are provided to demonstrate the proposed strategy.
