Modified projected cross point control — a large signal analysis

Modified projected cross point control (PCPC) is introduced and discussed in this paper. Compared to the existing PCPC method, the hardware implementation of the proposed modified method is simpler. This modified PCPC method benefits from the advantages of traditional fixed- and variable-frequency current mode control approaches. For instance, as argued in this paper, while modified 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 scheme. Other advantages and large-signal characteristics of modified PCPC are discussed by comparing it with the well-known peak and average current mode control methods.
