A switching regulated DC power supply is described for regulating the direct current to an inductive load. The power supply consists of: a dc power source; an inductive load; a bridge circuit including first and second input terminals connected respectively to opposite polarity terminals of the power source, first and second output terminals of corresponding polarity to the first and second input terminals connected across the load, a first unidirectional current conducting switching means forming a first leg of the bridge circuit for conducting current from the first input terminal to the first output terminal in response to a first control signal applied to a control input thereof, a second unidirectional current conducting switching means forming a second leg of the bridge circuit for conducting current from the second output terminal to the second input terminal in response to a second control signal applied to a control input thereof, a first diode device connected between the first input terminal and the second output terminal to allow load current to flow therethrough when the second switching means is switched off and a second diode device connected between the second input terminal and the first output terminal to allow load current to flow therethrough when the first switching means is switched off so that when both of the first and second switching means are switched on current flows from the source to the load when the first and second switching means are switched off current flows from the load to the source.
