Title: Controller of charging power generator
Inventor: MORI YUICHI
IPC: H02P9/30
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To prevent malfunction of external control without field current control depending on an external control signal when this current does not have the predetermined time change. SOLUTION: An external control signal judging circuit 146 is provided in a field current controller 14 of a charging power generator 1. In the external control signal judging circuit 146, the external control signal (C terminal signal) having the predetermined frequency is judged as the normal signal and the field current is controlled depending on the external control signal. For the other signals, the field current is controlled by a voltage control circuit 145 without relation to external control signal.  Thereby, when a fault (disconnection of signal line, short-circuit to the power supply line or to the earth) is generated in the external control signal and when a circuit current flowing at the earth changes due to ON/OFF of the electrical load to generate variation of earth potential, irregular rise of generated voltage stop of power generation are never generated and power generation can be continued under the predetermined voltage.
