IPMSM Drive with Interleaved Front End Buck Boost Converter for EV Application

Abstract

In this paper, a PhotoVoltaic(PV) array and battery powered Interior Permanent Magnet Synchronous Motor(IPMSM) for Electric vehicle(EV) application along with its design aspects is presented. The PV array works under Maximum Power Point Tracking(MPPT) condition using the Incremental Conductance(InC) algorithm to power the IPMSM during motoring and to charge the battery during braking. The motor is powered during non-sunshine hours by the battery through an Interleaved bidirectional buck-boost converter. The high performance of the motor is achieved using Direct Torque Control with Space Vector Modulation(SVM-DTC) of the IPMSM. SVM-DTC is an important control technique used in motor drives to obtain torque control and high-speed response. Along with modelling of motor and design of PV system, bidirectional converter design is discussed. Results for speed and torque control by the SVM DTC in various driving modes are presented.
