Patent ID: 7477533

Claim:
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 containing a 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, and a first switching regulator control circuit powered by the startup regulator for regulating switching of the first power FET, a converter and isolation circuit having a 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.
