  • Patent number: 5942818
    Abstract: This invention relates to a control apparatus for permanent magnet type generators, having a voltage control unit for controlling a voltage of a permanent magnet type generator driven by an automobile engine, and a power conversion unit for converting the DC source power of an automobile into commercial AC power during the stoppage of the engine. The voltage control unit is capable of reducing the number of large current switching elements, being formed to small dimensions and weight and having economically advantageous effects, and comprises an engine-driven permanent magnet type generator, a voltage step-up and rectifying circuit for increasing the voltage of output power generated by the generator, and a conversion circuit adapted to convert an output from the voltage step-up and rectifying circuit into three-phase AC power by a pulse-width modulation control system, and having a voltage step-down function.
