Abstract
A switching DC-DC converter unit is disclosed that includes an input for receiving a first DC voltage from a DC power source and switching circuitry coupled to the input to generate a switched alternating voltage from the first DC voltage. The switching circuitry includes a plurality of semiconductor switches having respective gate, source and drain leads, and further including noise suppression elements disposed on the drain leads. The unit further includes transformer circuitry coupled to the output of the switching circuitry and conversion circuitry disposed at the output of the transformer circuitry to convert the switched alternating voltage to a second DC voltage.
