Motor Power Inverter (MPI) Module

The MPI module converts 100 V DC power into 3-phase AC power to run the electric motor during assist.

During regeneration, the MPI module converts AC voltage to DC.

The MPI module is air cooled. The heat from the heat sink is exhausted to the cargo area by the IPU module fan.
