摘要:
Apparatus, systems, and methods are provided for reducing a potentially damaging high voltage fault condition in an alternator system. The apparatus comprises a motor, a rectifier coupled to the motor, an output node coupled to the rectifier, and a switch coupled between the rectifier and the output node, wherein the switch is a normally “on” switch. The system includes the apparatus implemented into a vehicle comprising an engine to drive the apparatus and a battery coupled to the apparatus, wherein the apparatus provides current to the battery. The method includes the steps of providing current from a rectifier of the alternator to a battery coupled to the rectifier and ceasing to provide current to the battery if a damaging event occurs, wherein the ceasing step comprises the step of switching OFF a normally “on” switch coupled between the rectifier and the battery if a damaging event occurs.
