1. An electrical converter comprising:

  • an alternating current plug body with electrical contacts extending perpendicularly from a front surface thereof for electrical engagement in a receptacle having a peripheral dimension, said plug body having a footprint less than the peripheral dimension of the receptacle, the electrical contacts extending rearwardly from said front surface and including an integral vertical arm supporting two circuit boards mounted proximate a front edge to opposite ends of the vertical arm and containinga power entry circuit with a line voltage input connected to at least one electrical contact and having at least one means for interrupting the line voltage input;

    a startup regulator having a first rectifier connected intermediate the power entry circuit and a regulation circuit charging a startup voltage storage capacitor, the startup regulator further having a feedback circuit for setting the startup voltage level;

    a power supply having a second rectifier connected to the power entry circuit and having;

    a power storage capacitor connected to the second rectifier,a first power FET connected to the power storage capacitor;

    an output inductor connected to the power FET, anda first switching regulator control circuit powered by the startup regulator for regulating switching of the first power FET,a converter and isolation circuit havinga first isolation device connected between the power supply output and a converter output,a second power FET controlling power through the first isolation device,a second switching regulator control circuit powered by the startup regulator and regulating switching of the second power FET,a feedback circuit for control of the second switching regulator control circuit,a connecting device connected to the electrical circuit and including a connecting device body received in an opening in the alternating current plug body distal the front surface and extending from the housing perpendicular to the front surface.
