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 7):
An engine generator, comprising:\n a general purpose engine, an engine speed of the engine being configured to be variably controlled; a generator unit having a three-phase winding and configured to be driven by the engine to generate power; an inverter unit configured to convert alternating current output from the generator unit to alternating current of a predetermined frequency to output to a load; a connection switching unit configured to switch a connection configuration of the winding to one of a wye-connection and a delta-connection; a load detection unit configured to detect a size of the load; and a CPU and a memory coupled to the CPU, wherein the CPU and the memory are configured to perform controlling the connection switching unit to switch the connection configuration to the wye-connection when the size of the load detected by the load detection unit 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 detected by the load detection unit is higher than the predetermined value.
