Embodiment Construction
[0022] An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a block diagram showing the structure of an engine generator. A (internal combustion) engine 2 is connected to a magnetic multi-pole generator (hereinafter simply referred to as "generator") 1 with field flux provided by permanent magnets, which generator 1 is driven by the engine 2 to generate multi-phase (typically 3-phase )comminicate. This alternating current is converted into direct current by full-wave rectification through a rectifier 3 , which is composed of a rectifier circuit bridge-connected with a silicon controlled rectifier as a semiconductor rectifier element, and input to an inverter 4 . The inverter 4 supplies single-phase AC at a commercial frequency (for example, 50 Hz) to an external load 5 connected to its output side. In order to adjust the opening degree of the throttle valve of the engine 2, a stepper motor 7 is provid...
