摘要
为满足工业自动化设备对高功率密度、高效散热及智能化控制的需求,以某3 kW伺服驱动系统配套供电模块为研究对象,设计一种基于控制器局域网(Controller Area Network,CAN)总线的液冷式直流-直流(Direct Current-Direct Current,DC-DC)电源模块。通过分析电感-电感-电容(Inductor-Inductor-Capacitor,LLC)谐振全桥拓扑结构特性,结合液冷散热方案与CAN通信协议,提出多模块并联均流控制策略与智能保护机制。仿真结果表明,模块在宽输入电压范围内输出稳定,效率在96%以上,功率密度超过21.44 W/cm^(3),通信延迟低于4 ms,具备良好的热管理性能与控制实时性。
