Abstract :
A novel single-phase current-source PFC with buck-type input is proposed. Input current is indirectly controlled by delta modulation of the input capacitor voltage to deliver near sinusoidal AC current at unity power factor. A resonant filter is employed to reduce the output inductor. Some experimental and simulation results are given.
