    摘要: A switched current power converter includes an input power source, an output terminal, and a plurality of current stages. Each of the current stages includes a converter coupled to the input power source for providing a current and a switch circuit that selectively couples the current in such current stage to the output terminal. A control circuit decouples the input power source from the current stage converters upon detection of a low load condition. Optionally, the power converter includes a low load circuit responsive to the control circuit that selectively couples current to the output terminal during the low load condition.

    摘要: A switched current power converter including an input power source, an output terminal, and a plurality of current stages. Each current stage includes a converter coupled to the input power source for providing a current, and a switch circuit for selectively coupling the current in such current stage to the output terminal. A control circuit selectively decouples the input power source from less than all of the current stage converters upon detecting a low load condition, thereby reducing circulating current losses and improving operating efficiency under low load conditions.
