Abstract
A power-factor-corrected switching power supply includes a power-factor-corrector cell followed by a current-fed dc/dc converter cell. Both cells operate in discontinuous current mode. A duty cycle modulator has its input coupled to the output of the current-fed dc/dc converter cell and its output coupled to the switch control inputs of both the PFC cell and the current-fed dc/dc converter cell so that both cells receive the same control signal.
