P0C0A Meaning

When three-phase alternating current flows through the three-phase windings of the stator coil, a rotating magnetic field is generated in MG2. The system controls the rotation of the magnetic field based on the rotor’s rotation position and speed. As a result, the permanent magnets provided in the rotor are pulled in the direction of rotation, generating torque. The generated torque is almost proportional to the amount of current. The system controls MG2 speed by regulating the frequency of the alternating current. Additionally, the system properly controls the rotating magnetic field and the angle of the rotor magnets to generate high torque efficiently, even at high speeds.

The Power Inverter Module, often called the Power Inverter Power Generator Module, contains two motor control modules and the hybrid powertrain control module. Each motor control module operates its respective drive motor generator based on commands from the hybrid powertrain control module. Each motor control module controls the speed, direction, and output torque of its respective drive motor generator through sequential activation of high-current switching transistors called Insulated Gate Bipolar Transistors. Each drive motor-generator operates using three-phase alternating current. Each Insulated Gate Bipolar Transistor operates a single phase of the drive motor generator. Each phase is individually identified as U, V, and W. Each motor control module monitors the temperature of each phase to detect inverter module overheating conditions.
