  • Reliable DC power supply
    Patent number: 6774507
    Abstract: A highly reliable power supply comprises two independent input power train units each connected to a separate primary winding of a common transformer, and an output power train unit connected to the secondary winding of the transformer. A control unit controls how much energy each of the input power train units supplies. Each of the input power train units is connected to a different source of battery power or a different power distribution bus. Advantageously the advantages of full duplication of a power supply are obtained while duplicating only the input power train units. The input power train units are effectively isolated from each other through being connected to separate windings of the transformer.
