2. DIAGRAM ALUR PENCAPAIAN KOMPETENSI

3. AUTOMOTIVE CHARGING SYSTEMS
YOU WILL LEARN: 1. PURPOSE OF CHARGING SYSTEM 2. CHARGING SYSTEM PRINSIPLE
3. CHARGING SYSTEM COMPONENT
4. TYPICAL OF CHARGING SYSTEM
5. HOW CHARGING SYSTEM WORK

4. PURPOSE OF CHARGING SYSTEM
CONVERT MECHANICAL ENERGY INTO ELECTRICAL ENERGY
RECHARGE BATTERY
PROVIDE POWER FOR ELECTRICAL ACCESSORIES
RESERVE POWER WHEN NEEDED

5. COMPONENTS OF CHARGING SYSTEM
BATTERY
ALTERNATOR
DRIVE BELT
VOLTAGE REGULATOR
CHARGE INDICATOR (LAMP OR GAUGE)

6. CHARGING SYSTEM PRINCIPLES
Faraday’s Law
When a conductor is driven in the magnetic fields, the induction currents will arise in the conductor

7. CHARGING SYSTEM PRINCIPLES
RIGHT HAND FLEMING LAW
When a conductor moved at magnet, the motive power will flow to the left

9. ALTERNATING CURRENT OPERATION
ELECTROMAGNETIC INDUCTION TO
PRODUCE ELECTRICAL POWER
VOLTAGE WILL BE PRODUCED IF MOTION BETWEEN A CONDUCTOR AND A MAGNETIC FIELD OCCURS.
2. AMOUNT OF VOLTAGE IS AFFECTED BY:
SPEED OF CONDUCTOR PASSING THROUGH FIELD
STRENGTH OF MAGNETIC FIELD
NUMBER OF CONDUCTORS PASSING THROUGH MAGNETIC FIELD

10. TYPICAL CHARGING SYSTEM
1. WITH MECHANICAL REGULATOR

11. TYPICAL CHARGING SYSTEM
2. WITH IC REGULATOR (COMPACT ALTERNATOR)

12. ALTERNATOR Alternator component: Front housing (drive end)
Rear housing (com end)
Stator
Rotor
Regulator
Brushes
Rectifier assembly
Brush holder

13. ALTERNATOR

14. ALTERNATOR ROTOR COPPER WIRE WOUND AROUND A IRON CORE
CURRENT PASSING THROUGH ROTOR CREATES A MAGNETIC FIELD
MAGNETIC FIELDS PRODUCE A VOLTAGE BY INDUCTION IN STATOR WINDINGS

15. ALTERNATOR ROTOR FIELD CIRCUIT Controls alternator output
Increased field current results in increased alternator output
Two brushes provide connection to field coil

16. ALTERNATOR Stator Three sets of windings around laminated core
Small gap between rotor and stator permits field circuit to energize windings of stator at the same time.

18. DIODE RECTIFIER Changes negative current into positive output
Converts ac (alternating) volts to pulsing dc volts
3 positive biased diodes
3 negative biased diodes
Number of poles on rotor and number of phases on stator will determine how smooth output is.

30. REGULATOR IC REGULATOR Advantage: Short timing regulation
More resistant to vibration
Small size shape
Disadvantage:
Less resintant to high temperature and fluctuation voltage

31. FROM TOYOTA ASTRA MOTOR STEP 2
IC REGULATOR PRINCIPLES WORK
When the output voltage at terminal B low:
Output voltage can not pass ZD So that Tr2 "Off" Output voltage to flow through the base resistor R Tr1 and Tr 1 "On" Flow to the rotor coil through B - rotor coil - F - Tr1 (on) - E (mass)
