Classification: H02M,Y02B

Abstract:
A power supply connectable with a power input to provide multiple regulated outputs, comprising:an input treatment network responsive to said power input to derive an interim voltage output of first value within a primary circuit domain;an inverter network within said primary circuit domain, responsive to said interim voltage and responsive to an inverter control input to derive an unregulated alternating voltage output of second value less than said first value at an output within a secondary circuit domain;an inverter control network coupled with said inverter network and deriving said inverter control input;a rectifier network within said second circuit domain responsive to said alternating voltage output to derive a distribution output at a d.c. voltage level corresponding with said alternating voltage output;a first d.c.-to-d.c. converter, within said secondary circuit domain responsive to said distribution output and to a first converter enable control input to derive a first one of said regulated outputs at a first voltage value;a second d.c.-to-d.c. converter, within said secondary circuit domain, responsive to said distribution output and to a second converter enable input to derive a second one of said regulated outputs at a second voltage value independent of said first one of said outputs; andcontrol circuit within said secondary circuit domain, electrically coupled with said first and second d.c.-to-d.c. converters and deriving said first and second converter enable control inputs.
