Abstract
The present invention provides an engine generator which is small in the size but high in the efficiency of power generation and a controller for the engine generator. The present invention is implemented by a power generator G driven by an engine E, a starter motor M for cranking the engine E, and a controller 4 for supplying various electric loads including the starter motor M with a driving voltage which depends on the power released from the generator G and a battery 5.
