This paper presents a digital signal processor (DSP)-based zero current detection (ZCD) and discontinuous conduction mode (DCM) digital detection method for the boost power factor correction (PFC) converter. The detection technique employs a DSP with integrated high-speed comparators to allow simple detection of zero inductor current and DCM operation. By avoiding the need for auxiliary circuits, inductor windings, and by effectively using DSP resources, the proposed detection technique realizes cost and performance advantages over alternative detection methods. An experimental 650 W boost PFC converter operating in mixed-conduction mode controlled by a TMS320F28035 confirms the effectiveness of the proposed detection technique.
