Abstract: Comparators of a rotary electric machine control apparatus acquire terminal voltages of each phase, which are developed at junction points between high-potential side FETs and low-potential side FETs, respectively. In switching over ON and OFF of the high-potential side FETs and the low-potential side FETs, a control unit determines a flow direction of a phase current supplied to each phase coil based on a terminal voltage developed in a dead time period, in which a the high-potential side FET and the low-potential side FET forming a pair are both turned off. Thus, the flow direction of each phase current is determined in a simple configuration.

Abstract: A magnetic component includes a plurality of coils, a magnetic core, and a shield. The coils form at least one of a primary coil and a secondary coil to which a voltage corresponding to a voltage induced to the primary coil is induced. The magnetic core penetrates through the coils. The shield is disposed at least one of between different coils in the coils and between one or more of the coils and the magnetic core. Each of the coils and the shield are respectively pattern-formed on substrates. Each of the coils and the shield have a stacking structure.
