In recent years, demand for efficient and reliable Electric Vehicle (EV) propulsion systems has surged, driving the need for advanced power control techniques. Henceforth, this paper introduces a novel contribution of High Gain Cuk converter with optimization approach for Brushless DC (BLDC) motor for EV propulsion. The proposed system leverages the High Gain Cuk converter, due to its ability to deliver high efficiency and voltage gain with minimized ripple currents, which is necessary to match the battery voltage with the required BLDC motor voltage. A novel control strategy, Siberian Tiger Optimized Proportional-Integral (STO-PI) Controller is introduced to improve efficiency and steadiness of converter under changing load circumstances. The STO method, inspired by the natural predatory behaviour of the Siberian tiger, is employed for tuning PI controller parameters. Simulation outcomes demonstrate that high gain Cuk converter combined with the STO-optimized PI controller, achieves higher performance compared to conventional approaches with regard to high efficiency of 94.54% with voltage gain of 1:7 and excellent dynamic response for BLDC motor. The implementation of this system contribute to the advancement of EV technology, particularly in regions with extreme climates, by enhancing the reliability, efficiency and driving experience of BLDC motor-based EV propulsion systems.

摘要

In recent years, demand for efficient and reliable Electric Vehicle (EV) propulsion systems has surged, driving the need for advanced power control techniques. Henceforth, this paper introduces a novel contribution of High Gain Cuk converter with optimization approach for Brushless DC (BLDC) motor for EV propulsion. The proposed system leverages the High Gain Cuk converter, due to its ability to deliver high efficiency and voltage gain with minimized ripple currents, which is necessary to match the battery voltage with the required BLDC motor voltage. A novel control strategy, Siberian Tiger Optimized Proportional-Integral (STO-PI) Controller is introduced to improve efficiency and steadiness of converter under changing load circumstances. The STO method, inspired by the natural predatory behaviour of the Siberian tiger, is employed for tuning PI controller parameters. Simulation outcomes demonstrate that high gain Cuk converter combined with the STO-optimized PI controller, achieves higher performance compared to conventional approaches with regard to high efficiency of 94.54% with voltage gain of 1:7 and excellent dynamic response for BLDC motor. The implementation of this system contribute to the advancement of EV technology, particularly in regions with extreme climates, by enhancing the reliability, efficiency and driving experience of BLDC motor-based EV propulsion systems.
