Abstract:
An engine generator, including a general purpose engine, an engine speed of the engine being variably controlled, a generator unit having a three-phase winding and driven by the engine to generate power, an inverter unit converting AC output from the generator unit to AC of a predetermined frequency to output to a load, a connection switching unit switching a connection configuration of the winding to one of a wye-connection and a delta-connection, a load detection unit detecting a size of the load, and a connection switching control unit controlling the connection switching unit to switch the connection configuration to the wye-connection when the size of the load is equal to or lower than a predetermined value, and to switch the connection configuration to the delta-connection when the size of the load is higher than the predetermined value.

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.
