An exemplary embodiment of an apparatus for supplying and switching power may include a power source, a transformer, a full bridge rectifier and a control switch. The transformer has a first winding and a second winding, the first winding being connected to the power source, the second winding having a first tap and a second tap, with the first tap being connected to a first load output. The full bridge rectifier includes four nodes, the first being connected to the second tap of the second winding, the second being connected to a second load output, the third being connected to a reference voltage source. The control switch is connected between a fourth of the four nodes and the reference voltage source.
