ABSTRACT:
The duty ratio range of a duty signal DCN transmitted from a high-voltage load controller 12 to a field current controller 103 is divided into several subranges, which are assigned to zones, such as a normal voltage control zone, high-voltage control zone, and power generation stop and failure signal zone. The duty signal of a duty ratio in each zone is transmitted to the field current controller 103 for controlling the power generation mode of a generator 2. When a failure in a high-voltage circuit 16 is detected, the duty signal of a duty ratio in the power generation stop and failure signal zone causes power generation of the generator to stop and a pilot lamp 10 to go on for warning. The pilot lamp 10 is also used to warn the operator to a power generation error of the generator 2.
