DC-DC基于超级电容的电梯弱电供电系统设计

摘要电梯是现代城市生活中最为常见的交通工具之一，是高层住宅和商业建筑的必备设施，同时也是楼宇中能源消耗的大户，因此近年来电梯的节能技术已经成为该领域的研究热点之一。

超级电容以物理储能的方式通过介质分离正负电荷，具有安全环保、充放电速度快、容量大、宽温度范围等特点。基于超级电容器的电梯节能技术主要通过对超级电容的充放电进行管理和控制，在超级电容储能丰富的情况下给电梯曳引机及弱电设备供电，储能不足时可切换至市电。84974

本文在理解超级电容工作原理的基础上设计了超级电容储能和放能整体结构，以具有32位数据处理能力的ARM-Cortex M3内核的STM32F103为核心，给出了最小系统电路、显示电路、变换电路以及整体的硬件原理图和软件编程设计，每个子模块的程序均在单独情况下进行了测试，验证有效。接着搭建了实验平台对DC/DC降压斩波电路进行了实验仿真，验证了超级电容充电放电的可行性。最后，基于电路原理图给出了电路PCB设计。

Title Design of Elevator Weak Current Power System Based on Super-Capacitor

Abstract Elevator is one of the most common means of transport in modern urban life。 It is a necessary facility for high-rise residential and commercial buildings, and is also considered as the large energy consumption in the field of building, so in recent years elevator energy saving technology has become one of the research hot spot in the field。

The super capacitor can separate positive and negative electric charge in the way of physical energy storage, and has the features of safety, environmental protection, fast charging and discharging speed, large capacity and wide temperature range, etc。 Based on the main idea of the super capacitor of elevator energy recovery technology, it focuses on the charge and discharge management。 If the super capacitor has adequate energy storage, it can provide the weak current equipment of the elevator with power; otherwise, if storage is inadequate, it can switch to grid。

Based on the understanding of the principle of super capacitor,this thesis gesigns the overall structure of the super capacit or energy storage and discharge energy。The minimum system circuit,display circuit,conversion circuit and the overall hardware schematic diagran and software programming are given in this thesis,using the STM32F103,which is the core of the ARM-CortexM3 kernel with 32 bit data processing capability。Each sub module program is tested in a single case,and it turns out that the result is effective。At last,PCB design is given on the basis of schemetics。

Keywords: elevator energy saving，energy storage，DC-DC，super capacitor
