Abstract
At least one example embodiment is directed to a power supply device. The power supply device includes a power factor correction circuit; a DC-DC converter; and one or more controller circuits configured to: monitor an output current of the DC-DC converter; detect, based on the output current of the DC-DC converter, one of a drop and an increase in the output current; and control the power factor correction circuit in response to the one of the drop and the increase in the output current.

A power supply device, comprising:
- a power factor correction circuit;
- a DC-DC converter;
- and
- one or more controller circuits configured to:
- monitor an output current of the DC-DC converter;
- detect, based on the output current of the DC-DC converter, one of a drop and an increase in the output current;
- and
- control the power factor correction circuit in response to the one of the drop and the increase in the output current.
A power factor correction controller comprising one or more circuits to:
- monitor an output current of a DC-DC converter;
- detect, based on the output current of the DC-DC converter, one of a drop and an increase in the output current;
- and
- control a power factor correction circuit in response to the one of the drop and the increase in the output current.
