回転機制御装置
Document Type and Number:
Japanese Patent JP7347341
Kind Code:
B2
Abstract:
A first terminal (T1) that is one end of a DC rotating machine (710) is connected to a phase current path of a multi-phase winding set. A multi-phase power converter (60) converts the DC power of a power supply (Bt) to multi-phase AC power by the operation of a plurality of inverter switches (IUH/L, IVH/L,IWH/L) connected in a bridge configuration and applies voltage to the respective phase windings (811, 812, 813) of the multi-phase winding set. DC rotating machine switches (MU1H/L) are constituted by switches on the high potential side and the low potential side, which are connected in series via a DC rotating machine terminal (M1), and make the voltage of the DC rotating machine terminal (M1) variable by switching. The DC rotating machine switch (MU1H) on the high potential side is constituted by a P-channel FET, and the DC rotating machine switch (MU1L) on the low potential side is constituted by an N-channel FET.
