DIY日记0-30V可调线性稳压电源
本人在深圳工作时买了几个大小不一的铝合金外壳（当时看到这些外壳挺漂亮就买了，一直闲置着），其中一个较大一点的外壳尺寸为：134x106x55mm。家里还闲置了一个功率约30W左右的小变压器（该变压器是从旧黑白电视机上拆下来的，有8V和18V两组输出），其厚度还刚好能装到这较大尺寸的铝合金外壳内。既然这么巧合，想不“撮合”它们都找不到理由了。那接下来就是考虑稳压电路部分了，0-30V可调稳压电路可以通过以下几个方案来实现：
（图13）
（图14）
步骤6——附件加工：
好马要配好鞍，接下来还要给电源制作一条漂亮的输出连接线见（图15），线材我选择音箱连接专用线，这种线材阻抗比较低，而且柔软，颜色也好区分。整条线含端子长度为：75cm，个人感觉这种长度使用起来非常舒适，还有一条长的备用线含端子长度为：120cm。
（图15）
步骤7——老化测试：
1.参考电压VREF：2.5V±0.4％（25℃）；
2.最大阴极电流范围：-100mA至+150mA；
3.最小阴极电流：0.5mA；
4.最大额定功耗：0.7W（TO-92封装）；
431内部结构和引脚排列如附图4所示；
6.TL431的典型应用电路如图5所示；
（图4）
（图5）
工作原理：
如图2所示，220V市电通过S1和F1连接到变压器的输入端，经过变压后分别输出：18V、8V、10V、3V（其中10V和3V绕组是自己以手工穿线的方式加绕的）四组电压，为了降低LM317T的功耗提高电源效率，采用了2个继电器的3级换档电路，换档电路如图6所示，电源输出电压V+加在W2的两端，当W2的滑动触片上获得的分压低于U4的VREF（2.5V）电压时，U4的K、A之间只有微弱的维持电流，J1因得不到足够高的工作电压，其常开触点断开，8VAC绕组通过J1和J2的常闭触点对后级电路供电；当W2的滑动触片上获得的分压高于U4的VREF（2.5V）电压时，U4的阴极电流剧增使J1得到足够工作电压，其常开触点吸合，18VAC绕组通过J1常开触点和J2的常闭触点对后级电路供电。由W3、J2和U5构成的另一级换档电路工作原理类同（可能有人会说换档电路也可以用运放来实现，当然是可以的，只是电路要复杂一点，要是做产品需要考虑成本我会用运放，但偏
TSXPCX3030使用手册
TSXPCX3030 USB-RS485串行多功能编程电缆概述：TSXPCX3030是通过USB接口提供串行连接及RS485信号转换的多功能编程电缆，本电缆的工作电源取自USB端口，不再由PLC的TER口供电，因此本电缆支持与PLC的TER或AUX口通信。
TSXPCX3030可用于Modicon TSX系列PLC与PC或其它不提供传统串行口的设备进行通信。
本电缆可与TSX Premium（57）、TSX Micro（37）、TSX Nano（07）、TSX Naza（08）及Twido PLC 的TER口或AUX口通信口相连。
TSXPCX3030编程电缆上配置有二个位置的拨动开关，用于选择不同的工作模式，摈弃了由PLC 控制RS485收发使能的方式，数据收发转换全部采用自动控制，可用于多点及点对点的应用。
TSX系列PLC的TER口有一个DPT信号引脚，用于确定该终端口的工作方式。
如DPT为高电平，则TER口总是工作在Uni-Telway Master（主站）方式，对PLC编程需在该方式下。
如果DPT 为低电平，则TER口的工作方式由PLC配置决定。
产品结构：开关M/S对应的工作模式特性及技术指标：●支持的操作系统Windows2000/Windows XP●完全兼容USB V1.1和USB CDC V1.1规范●USB总线供电，消耗电流约50mA●波特率：300bps～1Mbps自动适应●适用于TSX Premium、Micro、Naza、Nano和Twido●每台PC只支持一根TSXPCX3030电缆●长度：2.5米，颜色：黑色使用方法：TSXPCX3030需要安装USB设备驱动程序才能使用，要与PLC通信还需要安装最新版本的Uni-Telway或MODBUS驱动程序。
支持TSXPCX3030的Uni-Telway版本：Win2K/XP V1.6WinNT4/95/98/Me/DOS 不支持支持TSXPCX3030的MODBUS版本：Win2K/XP V1.1WinNT4/95/98/Me/DOS 不支持这些驱动程序均包含在随产品发售的光盘上，安装方法请看驱动程序光盘上的说明文档资料，此处不再赘述。

是很复杂啊。。看的人头晕。 不过既然是工厂批量生产，上市大量销售的机型，相信从电路结构、生产工艺、成本考量、稳定性等多方面都是经过确认的了。没哪家工厂不愿意删繁就简，更省事地造产品的。龙威 的这种机型，也只能算是价格实惠的实用型产品吧。应该是不会用高成本的复杂电路的。 补上这个原理框图看起来就简单省事了。呵呵。顺便也上个实物靓照。看起来直观一些。。

功率30W的小型开关电源方案分享之主电路设计
功率30W的小型开关电源方案分享之主电路设计
小型开关电源是目前民用家居领域的设计重点方向之一，本文将会通过今明两天的分享，为各位工程师们分享一种基于基于ICE2A365的30W开关电源设计方案，以便于工程师在平时的设计过程中进行参考。
在今天的方案分享中，本文将会就这一稳压型开关电源的主电路和控制电路设计情况进行简析。
系统整体设计
本文所设计的这一基于ICE2A365的稳压型开关电源，其原理框图如下图图1所示，其电路原理如下图图2所示。
这一小功率的开关电源，其输出功率为30W，选择使用ICE2A365芯片来完成设计。
图1 开关电源原理框图
图2 开关电源系统图
从图2所提供的这一30W小功率稳压开关电源的系统设计图中可以看到，在这一小功率开关电源的系统中，220V的市电交流电压先经过电源噪声滤波，该部分电路的目的是减少电磁干扰;再通过桥式整流和电容C7滤波后得到直流高压。
该高压供给高频变压器的初级绕组，在高频脉冲的作用下，电路处于开关状态，从而使电压通过变压器耦合到次级，副绕组给控制芯片电源提供电压，次级再经过肖特基二极管MBR20100整流和滤波电路I2、
C10、C12滤波，最后通过TL43l给输出提供一个2.5V的基准电压。
其输出。
