1. a power-converting device, possesses and multiplely connects multiple identity transformation device and the arm formed by cascade shape, it is characterized in that possessing:

  • Make the parts offsetting from each other the value of regulation between the identity transformation device of the phase place of the switch drive carrier wave of above-mentioned identity transformation device in said arm;

    Make the parts of action under the state making the switch drive of above-mentioned identity transformation device year wave frequency be greater than the value obtained divided by the quantity of the identity transformation device in said arm by the peak frequency of the audio-band of people;

    Synchronizing signal maker, for each official hour, generates synchronizing signal;

    AndCarrier generator, generates the switch drive carrier wave of the corresponding identity transformation device in each arm,Wherein, the carrier wave of constituent parts converter has offset from each other prescribed phases,Above-mentioned carrier generator using above-mentioned synchronizing signal as input, when phase place compared with above-mentioned skew also has further skew, the phase place of the carrier wave of the corresponding identity transformation device in each arm is made to carry out offseting and generate above-mentioned switch drive carrier wave in the phase locked mode of carrier wave.
