Systems and methods for powering a load

A power control module, comprising:

• a first input of the power control module configured to receive an input power from a power source;
• a second input of the power control module configured to receive a feedback 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 feedback signal at the second input,
• wherein the feedback module has an output electrically coupled to the second input of the power control module and is configured to output the feedback signal responsive to a signal received at a first input to the feedback module from the PFC output and an input parameter received at a second input to the feedback module, wherein the input parameter controls a logic circuit of the feedback module to output one of a plurality of reference voltages for controlling an amount of voltage delivered via the PFC output, and
• wherein the input parameter is 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, wherein the PFC includes a first PFC input configured to receive the electrical power, a second PFC input configured to receive a feedback signal from a feedback circuit, and a PFC output configured to deliver power, wherein the feedback circuit includes an output electrically coupled to the second PFC input and is configured to output the feedback signal responsive to a signal received at a first input to the feedback circuit from the PFS output and an input parameter received at a second input to the feedback circuit, wherein the input parameter controls a logic circuit of the feedback circuit to output one of a plurality of reference voltages for controlling an amount of voltage delivered via the PFC output;
• 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.
