Abstract: PROBLEM TO BE SOLVED: To derive power efficiently from a low-voltage AC power supply to supply it to a load.
SOLUTION: A power converter 1 includes an MERS 100 and a control means 105, and is connected in parallel between a series circuit composed of an AC power supply 210, a resistance R, and a reactor L and a load 300.

Abstract: PROBLEM TO BE SOLVED: To provide a protected power conversion device, capable of automatically interrupting a large current when it flows and executing DC-AC conversion using a full-bridge MERS (magnetic energy recovery switch), and to provide a control method. SOLUTION: The protected power conversion device 1 is composed of a full-bridge MERS 100, a control circuit 200, and an ammeter 300, and is connected between a DC power supply 2 and an inductive load 3. The ammeter 300 measures a current value supplied to the inductive load 3. The control circuit 200 switches four reverse conducting semiconductor switches SW1-SW4 configuring the full-bridge MERS 100, thereby converting the power outputted from the DC power supply 2 to AC power and supplying the converted AC power to the inductive load 3. Further, if a large current flows due to a short-circuit failure of the inductive load 3 and the ammeter 300 detects a current value not less than a predetermined value, the control circuit 200 turns off all the reverse-conducting semiconductor switches SW1-SW4 to interrupt the current.

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.
