ABSTRACT:
A motor vehicle electrical system having an engine-driven generator for supplying electrical loads on the vehicle, and a semiconductor switch connected in series with the field winding of the generator for on-off control of its excitation. The generator output voltage is constantly compared with a reference voltage in order to provide a duration modulated pulse signal. During steady-state operation, when the sensed generator voltage develops higher than the reference voltage during each prescribed period of time, the switch is biased on and off by the first duration modulated pulse signal. In the event of an abrupt rise in energy requirement from the loads, when the sensed generator voltage does not grow higher than the reference voltage within the preset time, a second duration modulated pulse signal is applied to the switch in order to make progressively longer the excitation periods of the generator field winding. The second duration modulated pulse signal is created mainly by a digital integrated circuit comprising two down counters.
