Abstract
In an example, a power factor corrector (PFC) including a first PFC input, a second PFC input, and a PFC output. The first PFC input is configured to receive an input power from a power source. The second PFC input is configured to receive a signal from a feedback circuit. The PFC output configured to output a direct current (DC) power, which is based on the input power at the first PFC input and the signal at the second PFC input. The feedback circuit is coupled to the PFC output and the second PFC input. The feedback circuit is configured to provide the signal at the second PFC input based on an input parameter related to a condition that is sensible by a sensor. The condition is related to operation of a load.

A power factor corrector (PFC), comprising:
- a first PFC input configured to receive an input power from a power source;
- a second PFC input configured to receive a signal from a feedback circuit;
- and
- a PFC output configured to output a direct current (DC) power, which is based on the input power at the first PFC input and the signal at the second PFC input,
- wherein the feedback circuit is coupled to the PFC output and the second PFC input, and
- wherein the feedback circuit is configured to provide the signal at the second PFC input based on an input parameter related to a condition that is sensible by a sensor, and
- wherein the condition is related to operation of a load.
A power control module, comprising:
- a first input configured to receive an input power from a power source;
- a second input configured to receive a signal from a feedback module;
- and
- an output configured to output to a supply power, which is based on the input power at the first input and the signal at the second input,
- wherein the feedback module is coupled to the output and the second input, and
- wherein the feedback module is configured to provide the signal at the second input based on an input parameter related to a condition that is sensible by a sensor, and
- wherein the condition is related to operation of a load.
A power buffer comprising:
- an input configured to receive an electrical power from a power factor corrector (PFC) during a first portion of a time interval;
- an energy storage device configured to store the electrical power received at the input during the first portion of the time interval;
- an output configured to be coupled to a pulse-width modulator (PWM), wherein the output is configured to, during a second portion of the time interval, output the electrical power stored in the energy storage device during the first portion of the time interval;
- and
- a control terminal configured to receive, from a control device, a control signal to control operation of the energy storage device.
