Power factor correction using projected cross point control (PCPC)

Projected cross point control (PCPC) is a new current-mode control approach which has been recently introduced. The PCPC method benefits from the advantages of traditional fixed-frequency and variable-frequency current-mode control methods. For instance, while PCPC is a fixed-frequency approach, it is stable for the entire range of the duty cycle similar to the variable-frequency hysteresis current-mode control (HCMC) scheme. In this paper, PCPC is used as the control strategy in a power factor correction (PFC) application. The results are compared with PFC methods based on the peak current-mode control (PCMC) and average current-mode control (ACMC) techniques.
