An integrated battery charger configuration for SRM drive in electric motorcycles

Abstract

Non-memberThis paper proposes and describes an integrated battery charger configuration for a switched-reluctance motor (SRM) drive to be used in electric vehicles such as electric motorcycles. The proposed configuration can share switching devices, inductors (motor-phase winding inductance), and a control board with the SRM drive. Moreover, it can be operated as a buck-boost converter, a buck converter, a boost converter, or a cascade buck-boost converter. In addition, for improved efficiency, additional high-frequency (small size) inductors can be added to the converter circuit to replace the inductors of the motor's winding coils. A 500-W 220-V experimental system was designed, constructed, and tested based on a 32-bit digital signal processor (TMS320F28027) with the use of SiC and Si MOSFETs as switching devices.

“…Integrated charger-inverters (ICI) allow using power electronic components as an inverter in driving mode and can be reconfigured by relays and contactors to be used as a charger in charging mode. Several possibilities have been reviewed, including single-phase input, three-phase input, multi-machine, multi-phase machine, and so on [3][4][5][6][7][8][9][10][11][12][13]. However, for motorcycle applications, only three-phase machines have been reasonably considered owing to their weights and volumes.…”
