| Abstract | Design and Implementation of a Switched Reluctance Drive Based on Miller Converter Student¡GChin-Lin Lu Advisors¡GMING-TSAN LIN Graduate School of Technology for Electrical Engineering Tung Nan University Abstract This thesis aims to develop a switched reluctance motor drive which is applied in electric scooter, in order to take consideration of system cost and performance, this research takes Miller converter circuit to simply the hardware circuit and reduce the output current ripple. Secondly, to avoid reducing the life of battery this thesis designs a regenerative charging circuit which is composed of ultracapacitors to absorb drastic current change due to the phase commutation. In order to reduce energy loss to enhance the endurance of electric scooter, the drive could convert the kinetic energy of scooter to electric energy and stored in the ultra-capacitors when electric scooter braking or going downhill. Then via the control of regenerative charging circuit to recharge the battery. To verifying the feasibility and reliability of the system design, a simplified switched reluctance drive was implemented. The drive uses a 32-bit digital signal processor as the control chip to executive algorithms of commutation control, current control, closed-loop speed control and regenerative charging control. Finally, through relevant experimental results validate that the design of the switched reluctance drive can match the needs of electric scooter drivers. Keywords: electric scooter, switched reluctance motors, Miller converter. |
