Abstract

This paper presents the energy recovery efficiency of a Brushless Direct Current (BLDC) motor drive. The primary application of this system is to power an energy-efficient e-rickshaw during regenerative operation. Notably, this work eliminates the need for an additional converter to manage reverse power flow, a crucial step towards realizing a sustainable green transport model. A novel two-boost control method is implemented to three phase Voltage Source Inverter (VSI) for bidirectional energy flow connected between battery and the BLDC motor. This approach not only facilitates the transfer of energy from the BLDC motor to the battery but also serves as an effective means of generating braking force. By comparing the proposed two boost method with the conventional single boost method, it demonstrates that the energy regenerated is significantly higher in this novel approach. To validate the findings, a real time testing on OPAL-RT LAB experimental set up has been used, which validate the results obtained through MATLAB/SIMULINK simulations. This paper contributes to the advancement of energy-efficient transportation solutions, aligning with the growing emphasis on sustainable and environmentally friendly modes of travel.
