摘要： A power conversion device including sub-inverters, each connected in series with respective phase of a three-phase main inverter including a smoothing capacitor, which is fed from a power supply via a converter, as a DC input thereof, and feeds power to a load using the sum of outputs of the inverters. A manipulative quantity is determined so that the DC voltage at each of smoothing capacitors which is an input of each of the sub-inverters will follow a command value. The manipulative quantity is added to an output voltage command for the three-phase main inverter, and is subtracted from an output voltage command for the sub-inverters. Thus, power is shifted from the three-phase main inverter to the smoothing capacitors of the sub-inverters.

摘要： A CR snubber circuit capable of increasing a reduction effect of the effective inductance component and suppressing a ringing component generated at the time of switching the switching element is obtained. A first current path formed on one surface of the substrate and a second current path formed on the other surface, which is the opposite side of the one surface of the substrate, are opposed to each other with the substrate being sandwiched therebetween, and the capacitor 5 and the resistor 6 are arranged such that current flows in opposite directions in the first current path and the second current path, and a band elimination filter is formed by the capacitor 5, the register 6, and an effective inductance component obtained by coupling an inductance component included in the first current path and an inductance component included in the second current path.
