Abstract: PROBLEM TO BE SOLVED: To provide an AC voltage control unit using one switch MERS for solving various problems in controlling an inductive load having current polarity. SOLUTION: The AC voltage control unit includes: an AC switch circuit; a capacitor connected to the AC switch in parallel for regenerating and accumulating magnetic energy of currents flowing through the inductive load when the currents of the AC switch circuit are interrupted; a control circuit for performing ON/OFF control by giving a control signal to the AC switch circuit; and a capacitor voltage detection circuit for detecting a point of time when both end voltages of the capacitor are turned to be almost zero, and for transmitting a command signal to turn on the AC switch circuit to the control circuit. Capacitance of the capacitor is turned to be a capacitor in a resonant state with the inductance component of an inductive load with frequency which is equal to or more than the frequency of the AC power source. The control circuit turns on the AC switch circuit by transmitting an ON control signal to the AC switch circuit in reception timing of the command signal, and then, transmits the control signal to turn off the AC switch circuit after the lapse of the preliminarily set ON time (time within the semi-cycle of the cycle of the AC power source).

Abstract: PROBLEM TO BE SOLVED: To provide an AC voltage control device capable of adjusting a voltage of an inductive load connected to an AC power source by a simple method.
SOLUTION: A magnetic energy regenerative switch in which a capacitor and an AC switch circuit are connected in parallel between an AC power source and an inductive load. After the AC switch circuit is turned on at the timing when the voltage of a capacitor is almost zero which occurs twice during one cycle of the AC power source, it is turned off when a preset time period (several milliseconds), which is the time required for charging/discharging of capacitor or more in a half-cycle of the AC power source or below, passes so that the current flowing the capacitor takes a route of the AC switch circuit only during a preset time period. By allowing a reactance voltage of the capacitor to be variable by extending/shortening the predetermined time period, a load voltage is adjusted.

Abstract: In order to provide a pulse power supply device using regenerating magnetic energy stored in a discharge circuit to a capacitor so as to use it as next discharge energy and supplying a bipolar pulse current with high repetition, a bridge circuit is composed of four inverse-conductive semiconductor switches, a charged energy source capacitor is connected to a DC terminal of the bridge circuit, and an inductive load is connected to its AC terminal. A control signal is supplied to gates of the inverse-conductive semiconductor switches, and a control is made so that when a discharge current rises, is maintained or is reduced, all the gates are turned off, and the magnetic energy of the electric current can be automatically regenerated to the energy source capacitor by a diode function of the switches. Further, a large-current power supply is inserted into a discharge circuit so as to replenish energy loss due to discharge, thereby enabling high-repetition discharge.

Abstract: PROBLEM TO BE SOLVED: To provide a small-sized and low-loss rectifier circuit capable of improving power factor.SOLUTION: Power outputted from an AC power supply AC is caused to be stored in inductors L1 and L2 as magnetic energy via a switch SW1 (or SW2) in an on-state.
