Dual winding system
|
| This system consists of two sets of three-phase windings whose phases are staggered 30°. Because the generated waves from the respective windings cancel out each other, magnetic noise is reduced. |

Hi side transistor
|
In the IC regulator adopted in the SC type alternator, Tr1 that regulates the rotor coil is installed at the high side.
HINT:
The circuit which has the switching element (transistors) at the positive (+) side opposed to the load (rotor coil) is called high side, while the circuit which has the devices at the negative (-) side is called low side. |
