Provided are a method and a device for controlling an internal combustion engine driven generator set to run in parallel. The method includes: each time an internal combustion engine is started, a controller detects whether a voltage is outputted in an out...

The present invention provides a multiple-frequency inversion method and a control apparatus for an internal combustion engine driven generator. An inverter unit employs a multiple-frequency inversion technology, controlling the inverter unit through a low...

An exhaust control valve /110) comprising a valve body (116) defining a fluid flow path through the exhaust control valve (110). A valve member (118) for controlling fluid flow rate along the fluid flow path is rotatably connected to the valve body (116). ...

Starting and stopping an engine is automatically controlled based on a load without using a relay An inverter engine-driven power generator (1) has an alternator (3), a rectifying circuit (51), a DC/DC converter (52), and an inverter circuit (53). A load d...

In a power supply apparatus having an engine operated generator, the operation of the power supply apparatus is improved in the efficiency in a light load region. The generator 1 is driven by the engine. The output of the generator 1 is converted into alte...
