Abstract
In a self-excited generatorincluding an automatic voltage regulator (AVR), a condensive load protection device includes: a field current control driverwhich is connected to the field windingin series and controlled to be ON/OFF by a drive circuitof the AVRto supply a field current to the field winding; and a condensive load protecting rotor short-circuit driverwhich is connected in parallel to the field winding, and supplies a short-circuit current to the field windingby being turned ON, and a bootstrap circuitis connected as a drive power supply of the field current control driver and the condensive load protecting rotor short-circuit driver, and the bootstrap circuitincludes a capacitance portionin which charges are accumulated when the field current control driveris ON.
