ABSTRACT:
Methods for power factor correction (PFC) and for reducing conduction losses and switching losses in a power converter as well as the power converter and phase management circuitry for the power converter. The power converter includes a first PFC pre-regulator interleaved with at least one additional PFC pre-regulator, and a step down converter. The average input power is measured downstream of the front end at the step down converter and the average current sense signal is compared to a reference voltage. Each additional PFC pre-regulator is disable when output power generated by the front end is less than a first pre-designated rated power level and each additional PFC pre-regulator is enabled when the output power is greater than a second pre-designated rated power level.
