Abstract:
1. A vehicle-mounted power generator set comprising: an AC generator mounted in a vehicle and driven by an engine which drives the vehicle; an electric power conversion portion that converts an output of said AC generator into an AC output having commercial frequency; a mode selection switch that is operated to be in different states between when a control mode is a power generation mode and when the control mode is a vehicle driving mode; a controller having electric power conversion portion control means for controlling said electric power conversion portion to generate an AC output having a fixed frequency from said electric power conversion portion when said control mode is the power generation mode, and engine control means for controlling said engine to rotate at a rotational speed suitable for supplying electric power from said electric power conversion portion to a load when said control mode is the power generation mode and controlling said engine to be suitable for driving of said vehicle when the control mode is the vehicle driving mode; and a power generation output supply control switch that is inserted between each output terminal of said AC generator and each input terminal of said electric power conversion portion, and controlled to be turned on/off in synchronization with said mode selection switch so as to be in an ON state when said control mode is the power generation mode and in an OFF state when said control mode is the vehicle driving mode.
