摘要： Embodiments of the disclosure relate to transient event mitigating systems and methods that can be incorporated into a power generation system. The power generation system can include an exciter coupled to an alternating current (AC) generator that provides electric power to power lines. The transient event mitigating system can include an automatic voltage regulator that detects a transient event in one or more of the power lines and configures a power converter to respond to the transient event by increasing an amount of direct current (DC) voltage coupled into the power converter. The power converter can provide the increased DC voltage to an exciter coil of the exciter for a transitory period of time in order to adjust the electric power generated by the AC generator and mitigate adverse effects of the transient event.

摘要： In a rotary electric machine, a modulation signal generator generates a modulation signal including information indicative of rotation of a rotor based on change of a voltage at an output end of a stator winding, and outputs the modulation signal. A rectifying unit alternately turns on and off the switch to rectify the voltage at an output end of the stator winding, thus generating a rectified voltage. An excitation current supplying circuit is communicably connected to the modulation signal generator via a communication line, and starts a supply of an excitation current to the excitation winding of the rotor to induce a rotating magnetic field in the stator winding when the modulation signal output from the modulation signal generator is input thereto via the communication line.

The apparatus also comprises determining and setting units. The determining unit determines whether a voltage of the battery satisfies a given condition for the voltage, by monitoring the voltage in a state where the generating operation of the generator is controlled. The setting unit sets, as an amount of offset of the charge/discharge current, a charge/discharge current detected when it is determined that the voltage of the battery satisfies the given condition.

摘要： In the battery charging device of the present invention, a U, V, W phase voltage generating circuit detects a voltage signal of a U phase sub-coil of a three-phase alternating current generator, and generates a signal of a triangular wave that is in synchronization with the U phase. Moreover, a first triangular wave is generated in synchronization with a phase from 0° to 180° of the U phase rectangular wave, and a second triangular wave is generated in synchronization with a phase from 180° to 360° of the U phase. In addition, a V phase rectangular wave is generated in which the level is inverted at a voltage point of two thirds the peak voltage of the first triangular wave, and in which the level is inverted at a voltage point of two thirds the peak voltage of the second triangular wave, and a W phase rectangular wave is generated in which the level is inverted at a voltage point of one third the peak voltage of the first triangular wave, and in which the level is inverted at a voltage point of one third the peak voltage of the second triangular wave.
