1. A DC-DC power converter system providing plural regulated DC outputs, each having a regulated voltage, comprising:

  • a DC input;

    a non-regulating isolating converter comprising;

    a primary transformer winding circuit having at least one primary winding that receives power from the DC input; and

    a secondary transformer winding circuit having at least one secondary winding coupled to the at least one primary winding and having plural controlled rectifiers, each having a parallel uncontrolled rectifier and each in circuit with a secondary winding, each controlled rectifier being turned on and off in synchronization with a voltage waveform of the at least one primary winding to provide a non-regulated, isolated DC output; and

    plural non-isolating switching regulators, each receiving power from the non-regulated, isolated DC output of the non-regulating isolating converter and each providing one of the regulated DC outputs having a regulated voltage.
