Abstract: PROBLEM TO BE SOLVED: To provide a low-loss power conversion device and the like, capable of supplying an AC current to a load with a small fluctuation of a peak value of the voltage supplied to the load.SOLUTION: In a device for supplying power from an MERS (magnetic energy regeneration switch) 100 connected to a power source VS, the load current flowing from the MERS 100 to a load is detected by a current detecting unit 300a. For the purpose of forming a path to begin charging the capacitor of the MERS 100, the timing for turning off the reverse-conducting type semiconductor switch of the MERS 100 is determined on the basis of the amount of the detected load current.
