1. A combined power supply and driver control module, comprising:

  • (a) a first connection for connecting the control module to an input power source;

    (b) a rectifier circuit connected to the first connection for rectifying input voltage received from the input power source and providing a rectified output for producing a DC power;

    (c) a switching device configured to receive the DC power and modulate input current received from the input power source;

    (d) control circuitry for controlling the opening and closing of the switching device to modulate the input current received from the power source, the input current received from the power source being modulated by the switching device to be closer in phase with the voltage of the power source;

    (e) a driver circuit connected to the switching device for providing an output power to a load; and

    (f) a second connection for connecting the control module to the load.
