1. An output variable type electric generator comprising:
an electric generator main body capable of switching a three-phase alternating current to be output between a low voltage and a high voltage by switching a wire connection pattern of armature coils,
the output variable type electric generator including an inverter output circuit and a standard output circuit between the electric generator main body and a three-phase output terminal block,
the inverter output circuit connecting the electric generator main body to the three-phase output terminal block through an inverter having a specification voltage corresponding to the low voltage or the high voltage,
the standard output circuit connecting the electric generator main body to the three-phase output terminal block without the inverter,
the output variable type electric generator further including an output format selector switch having at least two switching positions including an inverter output position for selecting an output through the inverter output circuit and a standard output position for selecting an output through the standard output circuit,
the output format selector switch including:
a wire connection switching section to switch a wire connection of the armature coils of the electric generator main body between a low voltage wire connection pattern and a high voltage wire connection pattern;
a connection switching section to switch a connection of the electric generator main body and the three-phase output terminal block between an inverter connection performed through the inverter output circuit or a standard connection performed through the standard output circuit; and
an interlocking mechanism to cause the wire connection switching section and the connection switching section to interlock with each other, and
the interlocking mechanism causing the connection switching section to perform the inverter connection and causing the wire connection switching section to switch to a wire connection pattern for generating a voltage corresponding to the specification voltage of the inverter when the switching position of the output format selector switch is in the inverter output position.
