1.No-load test (inspect charging circuit without load)
In the no-load test, whether the generated voltage is maintained at a constant level (regulated voltage) is cheeked even if the alternator speed (more…)
Charging System
SC Type Automotive Alternator
An SC type alternator adopts a joined segment conductor system (insert the segment conductor and weld it) to the stator winding method. This type of alternator can reduce the resistance value by half comparing (more…)
Automotive Output Control by IC Regulator
The following explains the mechanism by which the IC regulator keeps the generated voltage constant and how it operates to achieve this function using a battery sensing type IC regulator as an example.
1.Normal (more…)
Regulate Generated Electricity
Self-control for maximum output current
A characteristic of the alternator is that the output current flows almost constant when it exceeds a certain speed (self-control operation).
Therefore, when (more…)
Alternator with Neutral-Point Voltage
Neutral-point voltage
(1)A conventional alternator uses six diodes to rectify three-phase AC (Alternating Current) into DC (Direct Current). The output voltages generated at the neutral point is utilized (more…)
Principle of the Automotive Alternator
2.Rectification
(1)Mechanism of rectification of alternator
Construction
The actual alternator forms rectification circuit called rectifier as shown in figure 1 to rectify three-phase alternating current (more…)
Function of Automotive charging system
Vehicle is equipped with many electrical devices to drive safely and comfortably. The vehicle requires electricity not only while driving but also while it stops.
Therefore, the vehicle has a battery (more…)
