The adoption of brushless direct current (BLDC) motor is a potential solution and is well suited for sustainable transportation applications, where energy efficiency and renewable power integration are critical. In this research, a photovoltaic (PV)-powered BLDC motor is proposed with the introduction of a novel converter and control strategy. The low voltage generated by PV system is improved utilizing quadratic high-gain boost (QHGB) converter, which steps up the voltage from PV to meet the requirement of BLDC motor. The converter’s operation is managed by an improved flower pollination algorithm (IFPA)-optimized proportional–integral (PI) controller, which dynamically adjusts the duty cycle based on real-time voltage requirements. This innovative approach not only enhances power conversion efficiency but also ensures a stable DC link voltage, critical for efficient motor drive operation. Furthermore, to ensure consistent supply of power availability, bidirectional DC–DC converter is incorporated into the system. This bidirectional converter facilitates both charging and discharging of the battery, enabling continuous motor operation and enhancing the system’s reliability. The validation proposed system is examined using MATLAB, and the results demonstrate that the proposed converter ranks with higher efficiency of 97.56%, compared to state of art approaches.

摘要

The adoption of brushless direct current (BLDC) motor is a potential solution and is well suited for sustainable transportation applications, where energy efficiency and renewable power integration are critical. In this research, a photovoltaic (PV)-powered BLDC motor is proposed with the introduction of a novel converter and control strategy. The low voltage generated by PV system is improved utilizing quadratic high-gain boost (QHGB) converter, which steps up the voltage from PV to meet the requirement of BLDC motor. The converter’s operation is managed by an improved flower pollination algorithm (IFPA)-optimized proportional–integral (PI) controller, which dynamically adjusts the duty cycle based on real-time voltage requirements. This innovative approach not only enhances power conversion efficiency but also ensures a stable DC link voltage, critical for efficient motor drive operation. Furthermore, to ensure consistent supply of power availability, bidirectional DC–DC converter is incorporated into the system. This bidirectional converter facilitates both charging and discharging of the battery, enabling continuous motor operation and enhancing the system’s reliability. The validation proposed system is examined using MATLAB, and the results demonstrate that the proposed converter ranks with higher efficiency of 97.56%, compared to state of art approaches.
