Abstract
A multiple output DC-DC converter comprises a transformer, a primary circuit, a plurality of secondary circuits, and a controller. The transformer has a primary and at least one secondary winding. The primary circuit connects to a DC power supply source and includes the primary winding of the transformer and a primary switch connected in series. The plurality of secondary circuits includes the at least one secondary winding of the transformer, wherein each secondary circuit provides a DC power supply output, and at least one of the secondary circuits has a secondary switch. The controller monitors an output signal of each secondary circuit and controls operation of the primary and secondary switches based on the monitored signals. The controller co-ordinates operation of the secondary switch with the primary switch, such that the primary switch and the secondary switch are switched on simultaneously, or with a controlled offset.
