Description

Generator (IC regulator)

The IC regulator controls the power generation voltage by the tar-
get power generation voltage based on the received PWM com-
mand signal.
When there is no PWM command signal, the generator performs 
the normal power generation according to the characteristic of the 
IC regulator.

ECM

The battery current sensor detects the charging/discharging cur-
rent of the battery. The ECM judges the battery condition based on 
this signal.
The ECM judges whether to request more output via the power 
generation voltage variable control according to the battery condi-
tion.
When performing the power generation voltage variable control, 
the ECM calculates the target power generation voltage according 
to the battery condition and sends the calculated value as the pow-
er generation command value to the IPDM E/R.

IPDM E/R

The IPDM E/R converts the received power generation command 
value into a pulse width modulated (PWM) command signal and 
sends it to the IC regulator.

Combination meter (charge warning lamp) 

The IC regulator warning function activates to illuminate the 
charge warning lamp if any of the following symptoms occur while 
generator is operating:
·Excessive voltage is produced.
·No voltage is produced. 

Battery current sensor

The battery current sensor is located on the negative battery cable 
terminal. The battery current sensor detects the charging/dis-
charging current of the battery and sends a voltage signal to the 
ECM according to the current value detected.
