Abstract: Prior DC to DC converters have required both closed-loop gating circuitry to control solid state switches and large output inductors. This typically has added both to the complexity and weight of the converters. In order to overcome these problems, a DC to DC power converter (10) having first and second input terminals (12, 14) and an output terminal (16) for providing an output voltage at the output terminal (16) which is at a potential halfway between a DC potential applied by a DC power supply across the first and second input terminals (12, 14) is disclosed. The converter (10) comprises first and second switches (34, 36) connected at a switch junction (37) in series across the first and second input terminals (12, 14), first and second series-coupled diodes (38, 40) coupled at a diode junction (41) across the first and second input terminals (12, 14) in reverse-bias relationship with respect to the DC potential applied across the first and second input terminals (12, 14), a transformer (42) comprising two windings (43, 46) inductively linked and having first and second ends (45, 46) and a center-tap (48), the ends (45, 46) coupled between the switch junction (37) and the diode junction (41) and the center-tap (48) coupled to the output terminal (16) and means (56) for alternately switching the first and the second switches (34, 36) at an equal duty factor.

Abstract: Prior DC to DC converters have required both closed-loop gating circuitry to control solid state switches and large output inductors. This typically has added both to the complexity and weight of the converters. In order to overcome these problems, a DC to DC power converter (10) having first and second input terminals (12, 14) and an output terminal (16) for providing an output voltage at the output terminal (16) which is at a potential halfway between a DC potential applied by a DC power supply across the first and second input terminals (12, 14) is disclosed. The converter (10) comprises first and second switches (34, 36) connected at a switch junction (37) in series across the first and second input terminals (12, 14), first and second series-coupled diodes (38, 40) coupled at a diode junction (41) across the first and second input termi­ nals (12, 14) in reverse-bias relationship with respect to the DC potential applied across the first and second input termi­ nals (12, 14), a transformer (42) comprising two windings (43, 46) inductively linked and having first and second ends (45, 46) and a center-tap (48), the ends (45, 46) coupled between the switch junction (37) and the diode junciton (41) and the center-tap (48) coupled to the output terminal (16) and means (56) for alternately switching the first and the second switches (34, 36) at an equal duty factor.
