Abstract :
The storage battery is established in DC side of three-phase rectifier, and this can be charged. Then, rectifier is operated as inverter, and it is possible to discharge the storage battery. In case of the resistive load, real alternating current becomes equal a command by instant current feedback control of the converter. However, real alternating current is different a little from the command by instant current feedback control of the converter in case of the storage battery. In this paper, this phenomenon and the countermeasure are clarified.
