Alternator voltage regulators are complex electronic circuits that adjust the voltage produced by the alternator in order to suit the demands of the car's electrical system. The schematic of an alternator voltage regulator consists of various components such as rectifiers, diodes, zener diodes, resistors, and transistors.. An automotive alternator is a three-phase generator with a built-in rectifier circuit consisting of six diodes, as shown in Figure 2. Figure 2. Automotive alternator schematic diagram . As the sheave (most people call it a pulley) is rotated by a belt connected to the automobile engine's crankshaft, a magnet is spun past a stationary set of.
