(Refer to Hybrid Control System - "HPCU (Hybrid Power Control Unit)".)
•
You need to perform resolver compensation whenever the engine, HPCU, drive motor, or starter generator (HSG) is replaced, removed, or reinstalled.
Perform compensation according to the GDS motor / HSG resolver compensation procedure shown below.
GDS Motor/HSG Resolver Compensation Procedure

    Diagram System CircuitA high-capacity power module is applied to the two high-voltage motors.The power module consists of a high - speed switching circuit that is isolated from the IGBT and DIODE circuits.

    Description• To efficiently control the drive motor, you need to know the absolute location of a motor rotor (permanent magnet).• Resolver detects the absolute location of the motor rotor.
