Current Mode Hysteresis Controlled Multi Input – SEPIC- Re-Boost-System


Objectives: To reduce the number of switches, reduce the torque ripples and to improve the dynamic response of closed loop-controlled- SEPIC-Re-Boost-Multi-Converter (SRBMC) system using suitable controller. Methods: This study introduces SRBMC to control speed of DC Motor using hysteresis controller. The utilization of hysteretic controllers for low voltage controllers utilized in PC and correspondence frameworks has been picking up enthusiasm due its different favorable circumstances. Favorable circumstances of this control approach incorporates quick reaction and vigorous with straightforward structure and usage. Findings: It was observed that torque ripple is reduced from 0.24 N-m to 0.003 N-m by using hysteresis-controller. The settling-time was from 4.5 sec to 2.3 sec by utilizing HC. The ‘steady-state-error’ in theoutput-voltage was diminished from 6.3 Rpm to 0.8 Rpm by introducing HC. Application: The applications include the battery charging, Tele communication systems, Electric vehicles and DC motor drives
