<p>PURPOSE:To enable controlling an output automatically by controlling a field current value when an output current or output voltage of a generator exceeds a set point. CONSTITUTION:An output of generating portion 3A of an engine generator 3 is supplied to a floodlight 1 and a general load 2. A voltage monitor means 5A outputs a control voltage Vs1 when an output voltage VL is more than a set point. A current monitor means 5B outputs a control signal Vs2 when an output current IL is more than a set point. An excitation control means 5C supplies a field current to a field coil 8 when the control signals Vs1 and Vs2 are not inputted thereto, and passes the field current of the field coil 8 to a flywheel diode 62 when the control signal Vs1 or Vs2 is inputted thereto.</p> |
