摘　　要：针对大功率超级电容充电特点和要求,利用高频开关电源技术,设计了一种三相交流输入的大功率智能充电机。采用全桥变换器作为主电路的主要拓扑结构,由IGBT专用驱动芯片驱动,利用软开关技术控制前后桥臂,同时设计欠压、过流、过热、短路、过压、缺相等保护电路和CAN通信接口,具有充电系统故障自诊断功能,充电过程与电池状态参数的存储、上传显示、历史数据查询等功能,实现智能充电和自动化管理;实验测试了充电机不同工作模式下的充电稳定精度和不同输出功率下的充电效率,结果表明充电机工作稳定可靠,充电效率高,满足超级电容对充电设备的要求。Aiming at the features and requirements when high-power supercapacitors were charged, high frequency switching power supply technology was applied to design a high-power smart charger with three-phase alternating current inputted. The main topological structure of main circuit consisted of a full-bridge converter which was driven by an IGBT driver IC and soft-switching technology was applied to control the leading bridge and lagging bridge. Not only did the charger have a CAN communication interface, but also a series of protection circuits were designed to avoid fault including under-voltage, over-current, overheat, short circuit, overvohage and default phase, so a fault self-diagnosis system was provided. The charger saved charging process data and battery status data and displayed these data by a LCD, meanwhile users could query historical data if need, thus smart charging and automated management was realized by the charger. We tested charging stabilizing accuracy in different working mode and charging efficiency in different output power, the results showed that the charger can work reliably and has a high charging efficiency, so it is suitable for the charging of supercapacitors.
