Abstract
PURPOSE:To simplify the regenerative circuit of the back electromotive force of a motor, and to prevent the breakdown of a circuit element by coupling a switching means and a flywheel means under a state, in which both means are insulated electrically by means of a pulse transformer. CONSTITUTION:When a switching transistor 3 is turned ON during the positive half cycle of an AC power 1, a switching transistor 7 for a flywheel is turned OFF, and the state in which currents are not flowed through a flywheel means 6 is brought. When the switching transistor 3 is turned OFF during the positive half cycle of the AC power 1, the switching transistor 7 for the flywheel is turned ON through a pulse transformer 5. Accordingly, back electromotive force induced in a motor 9 is regenerated by the motor 9 itself.
