Abstract

Sensorless Brushless Direct Current (BLDC) motors are widely used in industrial applications due to their high efficiency and low maintenance requirements. However, commutation based on Back-Electromotive Force (Back-EMF) zero-crossing detection is highly susceptible to noise, leading to commutation timing inaccuracies. This paper proposes an improvement in sensorless BLDC motor commutation performance through the application of a Finite Impulse Response (FIR) digital filter to the Back-EMF detection signal. The FIR filter is designed to attenuate high-frequency harmonic components without compromising system stability. The proposed method is implemented on a three-phase inverter system employing six-step commutation controlled by a microcontroller. Simulation results indicate that the dominant noise frequency in the Back-EMF signal is reduced from 347.6 Hz to 212.5 Hz after filtering. Furthermore, hardware experimental results demonstrate a reduction in disturbance frequency from 317.23 Hz to 265.43 Hz. The application of the FIR filter improves the reliability of zero-crossing detection and enhances commutation timing accuracy compared to an unfiltered system. These results confirm that the proposed approach is effective in improving the commutation performance of sensorless BLDC motors based on Back-EMF detection.

Abstract

Electrifying Indonesia’s motorcycle fleet is critical for reducing urban emissions and fossil fuel dependence. This study experimentally evaluates three powertrain configurations—hub motor, continuously variable transmission (CVT), and single-gear ratio—for converting internal combustion engine (ICE) motorcycles to electric two-wheelers (E2W). Using a Honda Vario 125 platform with a 72 V, 3 kW Brushless DC motor and 1.44 kWh lithium-ion battery, performance was assessed via chassis dynamometer and real-world urban road tests. The single-gear ratio configuration demonstrated superior overall performance, achieving 5.15 kW peak wheel power, 188.7 N·m torque, fastest acceleration (0–128 km/h in 22 s), and highest energy efficiency (37.0 km/kWh), enabling a 51.8 km range per charge. The hub motor excelled in top speed, while the CVT consistently underperformed. Benchmarking shows up to 104 % efficiency improvement over prior designs. These results provide quantitative guidance for converters, manufacturers, and policymakers, establishing the single-gear ratio as the optimal solution for urban and commercial E2W applications and supporting sustainable mobility initiatives.

Abstract

This study presents the design, implementation, and short-term experimental validation of a standalone solar-powered smart street lighting system integrating LED illumination, CCTV surveillance, and Internet of Things (IoT)-based real-time monitoring within a single pole-mounted platform. Load profiling identified a total energy demand of 1176 Wh/day, which increased to 1529 Wh/day after applying a 30% design margin. These requirements guided the selection of a 460 Wp monocrystalline photovoltaic module, a 40 A maximum power point tracking charge controller, and a 12.8 V, 150 Ah LiFePO₄ battery. Laboratory testing demonstrated the expected bulk/MPPT, boost, and float charging stages, while accelerated battery testing at 0.27C measured a capacity of 151 Ah. During five consecutive days of field testing under sunny to partly cloudy conditions, the post-charging state of charge (SOC) ranged from 90.0% to 97.2%, while the next-morning SOC ranged from 58.6% to 68.4%. The average nighttime SOC reduction was 32.8%, with a range of 25.1% to 37.3%. The IoT platform provided real-time monitoring of photovoltaic generation, battery condition, and load operation, while maintaining communication availability above 99% during the observation period. These results demonstrate short-term autonomous operation and technical feasibility under the observed field conditions. Longer seasonal testing and a complete life-cycle economic assessment remain necessary to evaluate long-term reliability and financial feasibility.

Abstract

Partial shading often introduces multiple local maxima into the power–voltage (P-V) characteristics of photovoltaic (PV) systems, which makes conventional maximum power point tracking (MPPT) methods prone to converging to suboptimal operating points. To overcome this challenge, this study proposes an Enhanced Artificial Rabbit Optimization (ARO)-based MPPT method by incorporating a time-varying adaptive inertia-weight mechanism, enabling more accurate global maximum power point (GMPP) tracking under nonlinear irradiance conditions. The proposed method was experimentally validated on a laboratory-scale PV platform consisting of three series-connected PV modules, a SEPIC converter, and an STM32-based controller tested under four irradiance patterns. The GMPP reference values were determined through direct experimental P-V scanning. The experimental results indicate that the enhanced method consistently performed better than the conventional ARO baseline, achieving a maximum output power of 98.68 W with a tracking accuracy of 99.93%. Across all test cases, the extracted power and tracking accuracy improved by an average of 1.24% and 1.21%, respectively, without a noticeable increase in tracking time.
