Power factor correction using projected cross point control (PCPC)

Abstract

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 currentmode control methods. For instance, while PCPC is a fixedfrequency 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.

Low cost single stage micro-inverter with MPPT for grid connected applications

“…The current through the main inductance is modulated by a Hysteretic Current Mode Control (HCMC) technique (Khazraei et al, 2010). A current loop is needed in this application in order to transform the inverter into a current source, (Lee et al, 2008), for the grid and to simplify the compensation for the voltage loop.…”
