回転機制御装置
Document Type and Number:
Japanese Patent JP7205519
Kind Code:
B2
Abstract:
To provide a rotary machine control device capable of simultaneously driving a multi-phase rotary machine and a DC rotary machine.SOLUTION: An ECU 10 (rotary machine control device) is capable of driving a three-phase motor 800 and a DC motor 710. A first terminal T1 which is one end of the DC motor 710 is connected to a phase current path of a three-phase coil set 801. An inverter (multi-phase power converter) 601 converts DC power of a power source Bt1 into three-phase AC power by operating a plurality of bridge-connected inverter switching elements IU1H/L, IV1H/L and IW1H/L, and applies a voltage to each phase coil of the three-phase coil set 801. A DC motor switch MU1H/L is constituted of high-potential-side and low-potential-side switches which are connected in series via a DC motor terminal M1. The DC motor terminal M1 is connected to a second terminal T2 of the DC motor 710. The DC motor switch MU1H/L varies a voltage Vm1 of the DC motor terminal M1 by switching.SELECTED DRAWING: Figure 5
