Abstract

PURPOSE:To improve responsibility and to reduce higher harmonic ripple by a method wherein when a transistor is turned OFF, first, a fly-wheel current is run, and if a current level does not restore the given value, then, a regeneration current is run to restore the given value. CONSTITUTION:When the set signal is positive, power supply is performed from the DC power source to the motor DM through transistors TR1, TR4 and if a current value reaches the given value, one of transistors TR1 and TR4 is turned OFF and a fly wheel current is run. Next, when the current value does not return to the given level after a certain time has elapsed, then, both transistors TR1 and TR4 are turned OFF and a regeneration current is run to a capacitor CO through diodes D2, D3 to quickly return the load current to the given level. And further, when the set signal is negative, power supply is performed from the DC power source to the motor DM through transistors TR3, TR2, and a fly wheel current is run as when the set signal is positive thus, the load current being returned to the given level.
