<p>PROBLEM TO BE SOLVED: To provide a power generator driven with an internal combustion engine, which can drive, without problems, a load for soft-start using a self- excitation type field rotary type AC generator as a power generator for driving an internal combustion engine and executing the slow-down control for lowering the number of rotations, under the non-load condition, moreover, without temperature rise in a field coil. SOLUTION: A relay 11, having a contact 11a which holds on state, when a load current does not flow and holds the off state when a load current flows, is provided. A capacitor C2 for increasing magnetization under the slow-down control is connected, in parallel with a capacitor excitation coil Wc of a self- exciting type field rotary AC generator 1 through the contact 11a.</p> |
