。[Claims for Utility Model Registration] A first DC power supply, a switching element connected between both ends of the first DC power supply via an inductive load, and a switching element having a polarity opposite to the first DC power supply. a diode connected in parallel to the load; a saturable current transformer having a primary winding inserted in a power supply path from the first DC power supply to the circuit including the load, the diode, and the switching element; A second DC power supply connected between both ends of a secondary winding of a saturation current transformer and a series circuit of a current limiting resistor, the saturable current transformer being controlled by the voltage of the first DC power supply. The voltage of the second DC power supply causes the secondary winding of the saturable current transformer to flow in the direction of the magnetic flux generated in the magnetic core of the saturable current transformer due to the current flowing in the primary winding of the transformer. The directions of magnetic flux generated in the magnetic core of the saturable current transformer due to the flowing current are set to be opposite directions, and the voltages of the first and second DC power supplies are respectively set as E 1 and E 2 , and the resistor When the resistance value of the transformer is R, the primary/secondary turns ratio of the saturable current transformer is 1:n, and the maximum load current flowing through the load is ILM, E 2 +nE 1 ≧ (LM/n) A switching power supply set to satisfy R.
