<p>A power supply control apparatus of an inductance load which makes power supply control such that a power supply current having a specified waveform is supplied to an armature coil during the high-speed revolution of a motor. Since a large inductance load needs a long time for the accumulation and discharge of magnetic energy, a chopper circuit is used for making power supply control with high response. The present invention serves to make power supply control of an inductance load with a low impressed voltage but with better response by use of reverse blocking diodes (6, 6a) and a capacitor (5) having a small capacitance.</p> |
