A chopper-stabilized power supply which comprises a switching transistor connected with an integrating filter between a source of unstabilized d.c. energy and a load circuit. A voltage comparator compares the output voltage of the supply to a reference voltage and delivers a rectangular control signal to a control transistor which controls the base current of the switching transistor. In the collector-emitter circuit of the control transistor, there is provided an inductor which is the primary winding of a transformer, the transformer also comprising a secondary winding connected in series with a diode to the base of the switching transistor for neutralizing the charge carriers present in the junction at each cut-off of the current of the control transistor.
