This thesis develops a switched-reluctance motor (SRM) drive with power type energy storage support. The SRM is powered from the mains by a bidirectional switch-mode rectifier (SMR). Its energy supplying quality and utilization are improved by the equipped supercapacitor at the DC-link. First, a digital signal processor (DSP) based elementary SRM drive is established. The asymmetric bridge converter with proper current control pulse-width modulated (PWM) scheme is constructed. Good driving characteristics are achieved with properly designed sensing, commutation, and control schemes. Under higher speed and/or heavier load, the commutation shifting and voltage boosting are further properly applied to enhance the driving performance.
Next, a three-phase bidirectional boost SMR is designed and implemented. After making detailed current ripple analysis, the energy storage inductor is designed. And through the properly designed constituted controllers, under well regulated DC output voltage, satisfactory line-drawn power quality is preserved simultaneously. Then a three-phase bidirectional SMR powered SRM drive is developed and evaluated. Except for satisfactory motor driving characteristics, successful regenerative braking operation is also achieved with the stored kinetic energy being sent back to the mains.
Third, a supercapacitor energy storage system is developed and used to provide an energy buffer for the SRM drive at its DC-link. To understand the energy conversion response characteristics of a supercapacitor, the key parameters of the employed supercapacitor bank are measured. Then the boost-buck DC/DC interface converter is constructed. Through proper designs of power circuits and controllers, the established supercapacitor possesses good charging and discharging characteristics.
Finally, the operation control of the whole SRM drive with supercapacitor energy storage buffer is conducted, and some measured results are presented to demonstrate its performance.
