Method and Apparatus for Power Control

A power control system, comprising:

• a power reduction module operable to reduce power to a load;
• a switching module operable to selectively transfer power directly to the load or to the power reduction module;
• a harmonic reduction module connected to an output of the power reduction module for reducing signal harmonics from power transferred to the load;
• a controller linked to the switching module;
• a resistor coupled between the switching module and the power reduction module;
• a resistor voltage monitor coupled to first and second terminals of the resistor, wherein the resistor voltage monitor measures a voltage across the resistor and sends voltage measurement data to the controller;
• and
• a low voltage monitor coupled between the power reduction module and the load, wherein the low voltage monitor measures a voltage across the load and transmits voltage measurement data to the controller, and the controller provides control signals to the switching module after comparing the voltage across the resistor to a first value and after comparing the voltage across the load to a second value;
• and
• wherein the load comprises a voltage range unit.
