ABSTRACT:
A DC to DC power converter having first and second input terminals and an output terminal for providing an output voltage at the output terminal which is at a potential halfway between a DC potential applied by a DC power supply across the first and second input terminal is disclosed. The converter comprises first and second switches connected at a switch junction in series across the first and second input terminals, first and second series-coupled diodes coupled at a diode junction across the first and second input terminals in reverse-bias relationship with respect to the DC potential applied across the first and second input terminals, a transformer comprising two windings inductively linked and having first and second ends and a center-tap, the ends coupled between the switch junction and the diode junction and the center-tap coupled to the output terminal and means for alternately switching the first and the second switches at an equal duty factor.
