A Novel PWM Technique in Digital Control
IEEE Transactions on Industrial Electronics（2007）
摘要
One problem with microprocessor-based high-frequency pulsewidth-modulation (PWM) converters is the modulating resolution limitation caused by limited-time resolution of hardware timers. In this paper, a novel PWM technique, the double PWM (DPWM), is proposed. DPWM combines the advantages of low-frequency modulation and high-frequency switching in power conversion and resolves the contradiction bet...
