Abstract

Conventional chargers often employ diode bridge rectifiers, which result in a low power factor and inefficient energy utilization. This research compares the Zeta converter against a conventional buck-boost direct current (DC) to DC converter in electric vehicles (EVs) application to enhance energy conversion efficiency, with particular attention to battery state of charge (SOC) and driving range. A Fractional Order Proportional Integral Derivative (FOPID) Controller is implemented to improve dynamic performance and system stability. The controller parameters are optimally tuned using the Mother Optimization Algorithm (MOA), a recent swarm intelligence-based metaheuristic inspired by maternal nurturing behavior. The fractional order proportional integral derivative (FOPID) controller regulates the Zeta converter's duty cycle through pulse width modulation (PWM). Results show a high efficiency of 99 % and a fast settling time of 0.19 s when supplying a resistive load at rated power. A low Total Harmonic Distortion (THD) of about 2 % was obtained under steady-state operation, while a significant voltage gain of up to 13 was achieved under rated input conditions. These outcomes demonstrate the effectiveness of the proposed system, highlighting its potential for extending driving range and reducing charging losses in real-world EV systems.

基于母优化FOPID控制器的电动汽车zeta变换器与传统DC-DC变换器的比较分析

传统充电器通常采用二极管桥式整流器，导致低功率因数和低效的能源利用。本研究将Zeta变换器与传统的buck-boost直流（DC）到直流（DC）变换器在电动汽车（ev）中的应用进行了比较，以提高能量转换效率，特别关注电池的充电状态（SOC）和行驶里程。采用分数阶比例积分导数（FOPID）控制器，提高了系统的动态性能和稳定性。控制器参数使用母亲优化算法（MOA）进行优化调整，这是一种基于群体智能的元启发式算法，受母亲养育行为的启发。分数阶比例积分导数（FOPID）控制器通过脉宽调制（PWM）调节Zeta变换器的占空比。结果表明，在额定功率下提供电阻性负载时，其效率高达99%，稳定时间仅为0.19 s。在稳态运行下获得了约2%的低总谐波失真（THD），而在额定输入条件下获得了高达13的显著电压增益。这些结果证明了所提出系统的有效性，突出了其在实际电动汽车系统中延长行驶里程和减少充电损失的潜力。
