MDM (Motor Driver Module)
The MDM consists of the MPI module, voltage converter module, capacitor, and the U/V/W phase motor current sensors. The voltage converter acts as a preamplifier for the IGBTs. The IGBTs are used to transfer electrical energy to the motor from the 144 V battery and vice versa. The IGBTs are activated by the MCM based on the amount of assist/ regeneration needed. The voltage converter module monitors voltage and temperature of the MDM, and sends this information to the MCM.
