  • High integrity dual input power supply
    Patent number: 4558230
    Abstract: A high integrity multiple output power conditioner operating from redundant dc sources utilizes circuits to combine the sources to share a load and provide source isolation in event of component failure in any one of plural converters employed. Multiple ground planes permit high integrity checking of individual operation of multiple power converters employed in the system.

  • Energy conserving drive circuit for switched mode converter utilizing current snubber apparatus
    Patent number: 4370701
    Abstract: An energy conserving drive circuit is provided for switched mode power converters having a transformer with primary current controlled by a main power switch whose conduction is in turn controlled by a pulse width modulator. Transformer leakage inductance energy is applied to drive the pulse width modulator and the main power switch in a run mode after start-up. The drive circuit includes an improved non-dissipative snubber network which supplies the drive power for the main power switch and which also disables a start-up circuit.
