モータ制御装置
Document Type and Number:
Japanese Patent JP7172522
Kind Code:
B2
Abstract:
To suppress ripple current of a frequency, which is six times as much as a frequency of output AC.SOLUTION: A motor controller comprises: a first inverter; a second inverter; and a controller. The first inverter converts power of a DC power supply into three-phase AC for driving a three-phase AC-type first motor. The second inverter is connected to the first inverter in parallel, and converts the power of the DC power supply into three-phase AC for driving a second three-phase AC type motor. The controller controls the first inverter and the second inverter so that the output AC of the first inverter and that of the second inverter have the same frequency and have a phase difference of (30+60×n) degrees (n is integer).SELECTED DRAWING: Figure 1
