SYSTEM AND METHOD FOR REDUCING POWER CONSUMPTION IN A POWER SUPPLY CIRCUIT

摘要

A system for reducing power consumption in a power supply circuit including: a transformer including: a core; a first winding including a first end and a second end of a first wire wound on the core; a second winding including a first end and a second end of a second wire, wherein the second wire has a larger cross-section than the first wire and the second end of the first wire is connected to the first end of the second wire; an input electrically connecting the first and second windings to the power supply circuit; and an output for connecting to a load; and a controller connected to the transformer for controlling an output voltage at the output, wherein the output voltage is less than a supply voltage at the input, to reduce the power consumption of the load.

1. A system for reducing power consumption in a power supply circuit including:
a transformer including:
a core;a first winding including a first end and a second end of a first wire wound on the core;a second winding including a first end and a second end of a second wire, wherein the second wire has a larger cross-section than the first wire and the second end of the first wire is connected to the first end of the second wire;an input at the second end of the second winding for connecting to the power supply circuit; anda movable contact having an output for connecting to a load, the contact positioned between the first end of the first winding and a junction positioned at the second end of the first winding and the first end of the second winding; and a controller for variably controlling an output voltage at the output, wherein the output voltage is less than a supply voltage at the input, to reduce the power consumption of the load.
