摘要： An electricity generation device includes a permanent-magnet electric generator with three or more phase windings each having one end serving as an output terminal and the other end connected to a neutral point, bidirectional semiconductor switching circuits connected between the respective phase windings and the neutral point and capable of interrupting connections between the respective phase windings and the neutral point, each bidirectional semiconductor switching circuit allowing current to flow therethrough in both directions in a conduction state and, after being input with a gate signal, retaining the conduction state by itself until the current stops flowing therethrough, a self-excited gate signal generation circuit for generating a gate signal for each of the bidirectional semiconductor switching circuits from AC voltages excited in the phase windings associated with others of the bidirectional semiconductor switching circuits such that the gate signal is output to one of the bidirectional semiconductor switching circuits during a period including the time at which the AC voltage excited in the corresponding phase winding turns from positive to negative and during a period including the time at which the AC voltage excited in the corresponding phase winding turns from negative to positive, and a startup gate signal output circuit for outputting a startup gate signal to all of the bidirectional semiconductor switching circuits when the permanent-magnet electric generator is to be started.
