Inverter (MCU) 

• An inverter supplies AC current to the drive motor and HSG.
• Depending on the driving conditions, the drive motor and HSG of the integrated board (control board) may act as a generator.

Integrated board (control board) 

• One CPU controls two motors (drive motor and HSG)
• Sensors send the position, current, and temperature information to the CPU. The CPU generates the pulse width modulation signal and sends it to the gate board.

Capacitor 

• Capacitor is an energy storage device for smoothing the current.

Current sensor 

• Current sensor measures the current that flows through the motor, and is attached to each phase of a 3 - phase busbar.

Power module 

• Power module has six switches that are used to convert DC current to AC current.

Heat sink 

• Heat sink dissipates the heat of the coolant and is located between the power module and the cooling path.
