Abstract
A voltage regulator for regulation of automotive electrical generators and battery system. A generator is coupled through a rectifier to a voltage regulator and a battery. The regulator is activated by a low voltage level stator signal from the generator. The activation voltage level is set to an improved initial activation time when the generator starts to charge the battery while maintaining tolerance to rectifier leakage current. A feedback is included in the regulator to lower power dissipation during regulation and protect the regulator during a voltage surge.
