摘要： PROBLEM TO BE SOLVED: To reduce variations in one cycle for the amount of magnetic energy accumulated in an inductive load and recovered as electrostatic energy in a capacitor of MERS.SOLUTION: A power converter 1 comprises a MERS 100, a control circuit 200 and a voltage detector VM, and is connected between an AC power supply VS and an inductive load LD. The voltage detector VM detects a voltage of a capacitor CM for the MERS 100. The control circuit 200 controls a voltage output from the AC power supply VS and supplies the voltage to the inductive load LD by switching four reverse conduction type semiconductor switches SW1 to SW4 constituting the full-bridged MERS 100. The control circuit 200 also controls the duty ratio of the reverse conduction type semiconductor switches SW1 to SW4 of the MERS 100 so that a peak voltage value of the capacitor CM becomes constant.

摘要： 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. When the switch SW1 (or SW2) is turned off, the magnetic energy is stored in a capacitor CM as electrostatic energy. The electrostatic energy in the capacitor CM is discharged to a load, after the completion of the discharging, the switch SW1 (or SW2) is turned on again. The on/off frequency and on-time of the switch are constant, thereby achieving current sensor-less and ideal PFC.

摘要： PROBLEM TO BE SOLVED: To provide a power conversion device and a control method that stably supply electric power to a load using an MERS even if a voltage has a zero crossing owing to noise.SOLUTION: The power conversion device 10 comprises the MERS 100 and a control circuit 200, and the MERS 100 is connected between an inductive load LD and an AC power source VS. The control circuit 200 starts counting in response to the zero crossing of the output voltage of the AC power source VS, and performs ON/OFF control over self arc-extinguishing elements S1 to S4 of the MERS 100 according to the count value. Here, the control circuit 200 resets its count value each time the output voltage of the AC power source VS has a zero crossing in every cycle, and restarts counting.
