摘要

混合动力汽车(HEV)是一种具有多种能源的电动汽车。混合动力汽车由电池、光伏(PV)或燃料电池供电。它需要通过双向变换器连接升压变换器来实现最大的功率输出。最大功率点是通过设置参考功率来管理双向变换器的占空比。本文介绍了采用模糊控制器控制的光伏电池混合动力汽车的设计。双向变换器用于调节电池的充电电流和放电电流。调节电流的目的是防止损坏电池，并减少铅酸电池中发生的气体现象。模糊控制器的设计是为了优化电池寿命和使用容量。仿真结果表明，双向变换器具有90%的效率，并能调节充电和放电电流。双向变换器也能稳定地保持输出电压。

Design of bidirectional converter using fuzzy logic controller to optimize battery performance in Electric Vehicle

Hybrid Electric Vehicle (HEV) is an electric vehicle which has more than one energy source. HEV is powered by battery, photovoltaic (PV), or fuel cell. It needs boost converter linked by bidirectional converter to achieve maximum power output. Maximum power point is achieved by setting reference power to manage bidirectional converter duty cycle. This paper shows design of HEV using PV and battery controlled by fuzzy logic controller. Bidirectional converter is used to adjust the charging current and discharging current of the battery. Regulation of the current is aimed to prevent damage to the battery, and reduces gassing phenomena that occurs in lead-acid batteries. Fuzzy logic controller is designed to optimize battery lifetime and used capacity. Simulation result shows that bidirectional converter has 90 percent efficiency and can regulate the charging current and discharging current. The bidirectional converter also can maintain the output voltage constantly.
