Abstract: An alternating current generation system is provided. In the system, in a rotor, a plurality of detection subject portions are arrayed along a circumferential direction in correspondence to reversal states of the magnetic poles in a plurality of magnetized portions. A detecting unit is disposed opposing the rotor so as to generate an output signal corresponding to passage state of the detection subject portions. A phase control unit outputs, to a power converter, a control signal to perform phase control of switching elements depending on the rotation phase of the rotor, based on the output signal from the detecting unit.

Abstract: A control apparatus for a motor-generator includes a stator including multi-phase coils, a rotor, a multi-phase inverter one arm of which includes a switch element and a free-wheeling element, and a power supply connected between a neutral point of the coils and a negative electrode of the inverter. When the switch elements are driven by rectangular wave, the low-side switch element connected to the high-side switch element is subject to PWM switching control while the high-side switch element is off. When a time point, at which the high-side switch element is turned off, is defined as a base point, if α is defined as a time when switching of the low-side switch element starts, and β is defined as a time when the switching ends, β-α is 120 degrees in electrical degree or more, α is more than 0 degrees, and β is less than 180 degrees.
