Design of integrated power module for electric scooter

This paper concerns the design of a general purpose integrated power module (IPM) for electric scooters. The basic design concepts of the IPM are to integrate the protection circuit into the gate driving circuit and dispose an anti-reverse connection device between an input end of the electric power and the motor controller. With that, the damage problem of the power board can be efficiently improved. Furthermore, the complexity of implementation of the control board is also reduced. Finally, the validity of proposed IPM is experimentally tested on a 2kW electric motor.
