Patent ID: 8653680

Claim:
A power generation control apparatus configured to drive a plurality of electric generators including a main electric generator and a subordinate electric generator, which are mounted on one internal combustion engine, at the same time by means of said internal combustion engine, characterized by comprising: a first power generation control device connected to said main electric generator; and a second power generation control device connected to said subordinate electric generator; wherein said first and second power generation control devices are each provided with: an external sensing terminal that detects an external voltage of an electric generator to which the external sensing terminal belongs; an output sensing terminal that detects a power generation voltage generated by said electric generator; and an external output terminal that outputs a signal synchronized with a field current control signal with respect to a field coil of said electric generator; wherein the power generation voltage of each of said electric generators is regulated to a target voltage value by carrying out field current control in which a field current is supplied to said field coil in an intermittent manner; and wherein when said plurality of electric generators are driven at the same time, the external output terminal of said first power generation control device and the external sensing terminal of said second power generation control device are connected to each other.
