Abstract
A rapid voltage drop due to generator output saturation is prevented by providing a generator output saturation detection means that extracts a generator output saturation detection signal from the collector terminal of the field transistor controlling the excitation current of the automotive generator and measures the duty ratio of the field transistor in the control device to detect saturation of the generator output, and a compressor control means for reducing the speed of the electrical compressor when saturation is detected.
