Abstract:
An engine generator, including an engine having a piston reciprocating inside a cylinder, a generator unit having a three-phase winding, driven by the engine to generate power and operating as an engine starter motor during engine starting, a power converter circuit connected to the generator unit, a battery supplying power to the generator unit through the power converter circuit during engine starting, an engine speed detection unit detecting an engine speed, a connection switching unit switching a connection configuration of the winding to one of a wye-connection and a delta-connection, and a connection switching control unit controlling the connection switching unit to switch the connection configuration to the wye-connection when the engine speed is lower than a predetermined engine speed, and to switch the connection configuration to the delta-connection when the engine speed is equal to or higher than the predetermined engine speed, during engine starting.

Claim (Index 6):
The engine generator according to  claim 5 , wherein\n the three-phase winding has a first winding, a second winding and a third winding, one end of each of the first winding, the second winding and the third winding being connected to the power converter circuit through each of a first terminal, a second terminal and a third terminal, other end of each of the first winding, the second winding and the third winding being connected to the switching circuit through each of a fourth terminal, a fifth terminal and a sixth terminal, and the switching circuit has a first switch, a second switch, a third switch, a fourth switch, a fifth switch, and a sixth switch, one end of the first switch being connected to the fourth terminal, other end of the first switch being connected to the second terminal, one end of the second switch being connected to the fifth terminal, other end of the second switch being connected to the third terminal, one end of the third switch being connected to the sixth terminal, other end of the third switch being connected to the first terminal, one end of each of the fourth switch, the fifth switch and the sixth switch being connected to each of the fourth terminal, the fifth terminal and the sixth terminal, other end of each of the fourth switch, the fifth switch and the sixth switch being connected to each other through a neutral point.
