Abstract: PURPOSE:To prevent the overvoltage puncture through imbalance of a three- phase inverter by equalizing the outputs of two inverters both in case of a variable voltage and variable frequency mode and in case of constant voltage and variable frequency. CONSTITUTION:In case of variable voltage and variable frequency, because an input power P2 to a three-phase induction motor 8 decreases after the operation of a difference volume detection circuit 13, an input current I2 to a three- phase inverter decreases and the terminal voltage EC2 of a filter capacitor 5 rises. Said operation continues so far as the circuit 13 detects a difference voltage  E so that the balance is recovered at the time of EC1=EC2. In case of constant voltage and variable frequency, further, contacts S1, S2 are switched to B side and the difference voltage  E is given as a controlled variable to chopper circuits 17, 18 by a command from a control mode determination circuit 21 to a switch circuit 22. In case of the difference voltage  E>0, the electric charge of a capacitor 4 is discharge through resistance 19 and the circuit 17 is turned OFF at the time of EC1=EC2. In case of  E<0, the charge of the capacitor 5 is discharged until EC1=EC2.
