Abstract: Disclosed is an integrated PFC and PWM controller with a plurality of frequency-load curves to minimize the no-load power consumption and maximize 4-point average efficiencies. The controller dynamically ushers the PFC and the PWM stage into HM, BM, DCM, or CCM on the most appropriate one among the plural frequency-load curves, cherry-picked based on the combined result from the input voltage and the output load sense signals, fetched from the input and the output terminals of the PFC and the PWM stage. All in all, the controller has the PSU operate in HM in case of no load, in BM in case of little load, in DCM in case of light load, or in CCM in case of heavy load across the flyback output rail.

Abstract: A power converting apparatus with dynamical driving adjustment includes a rectifying unit, a power factor correction unit, a power conversion unit and a feedback unit. The rectifying unit rectifies an AC input power to generate and transfer a DC power to the power factor correction unit for performing power factor correction. A power factor correction power is generated and transferred to the power conversion unit. The feedback unit is electrically connected to the power conversion unit to form a closed control loop. A PWM driving controller of the power conversion unit performs an adjustment process to control a switching transistor based on a feedback signal from the feedback unit, and the power conversion unit converts the power factor correction power into an output power supplied to an external load. Thus, the margin for electromagnetic interference is increased, and both switching loss and conduction loss are considerably reduced.
