GENERATOR [i-ELOOP]
id131704501000
Purpose, Function
• A variable voltage type generator has been adopted for the generator which can generate 12—24.3 V according to the capacitor (i-ELOOP) storage conditions.
Construction
• The generator is located on the left side of the engine (vehicle front side).
• The generator consists of the following parts:
• To handle a maximum of 24.3 V, the voltage resistance performance of the diode has been improved.
• The IC regulator built into the regulator component has the following protection functions which function during overheating/over-voltage/over-current.
Excess temperature protection function
-
― If the IC regulator reaches the specified temperature, the generator output current is restricted to suppress a rise in the temperature of the generator.
Excess voltage protection function
-
― If an excess excitation current control signal from the PCM is input, the generator output voltage is restricted to suppress application of excess voltage to the capacitor (i-ELOOP).
Excess-current protection function
-
― If the excitation current reaches the specified value, the excitation current is interrupted to restrict power generation by the generator.
• The initial excitation current to the rotors is supplied from the capacitor (i-ELOOP). When excitation current is supplied from the capacitor (i-ELOOP) and the generator begins generating electricity, the excitation current from the capacitor (i-ELOOP) is interrupted. After the generator begins generating electricity, the power generated by the generator is used for excitation current.
