Classification: CPC H  Y | IPC H

Claim 9:
10. A method comprising:
configuring a flyback power converter to perform a power factor correction on an ac power source and generate a regulated dc voltage fed into a load;
upon detecting that input energy from the ac power source is less than output energy required by the load, transferring energy from an energy storage device of a ripple cancellation apparatus to a magnetic core of the flyback power converter until a sum of the energy from the ac power source and the energy transferred from the energy storage device is approximately equal to the output energy required by the load; and
upon detecting that the input energy from the ac power source is greater than the output energy required by the load, transferring energy from the magnetic core of the flyback power converter to the energy storage device until energy in the magnetic core of the flyback power converter is approximately equal to the output energy required by the load.
