HYBRID CONTROL SYSTEM


  1. SYSTEM CONTROL


    1. The inverter converts the direct current from the HV battery into alternating current for generator (MG1) and motor (MG2), or vice versa. In addition, the inverter takes power generated by generator (MG1) and supplies it to motor (MG2). However, the electricity generated by generator (MG1) is converted into direct current inside the inverter before being converted back into the alternating current by the inverter for use by motor (MG2). This is necessary because the frequency of the alternating current output by generator (MG1) is not appropriate for control of motor (MG2).

    2. The MG ECU controls the IPMs for switching the three-phase alternating current of generator (MG1) and motor (MG2) in accordance with the signals received from the power management control ECU.

    3. When the power management control ECU has received an overheating, overcurrent, or voltage fault signal from the MG ECU, the power management control ECU transmits a shut down control signal to the MG ECU, in order to turn off the IPMs.
