It can achievd ZVS over the full input voltage range. This thesis proposes a triangular current-mode control without an external zero current detection circuit. In this thesis, average current-mode control is used to achived high power factor. The period of the duty cycle is calculated using the average current reference, input voltage, and output voltage. PSIM simulation is utilized to verify the feasibility of the proposed control method. Finally, the 800-W bridgeless TPPFC with the proposed control is implemented with the switch frequency around 60 kHz-180kHz, an input voltage of 230 Vrms, and an output voltage of 400 V.
