辉光钟

感谢微软工程师Kevin的详细评测！
A big thanks to Kevin, a Software Engineer at Microsoft, for his professional and detailed review. He did a great job making a nixie clock of his own, using my NCH6100HV as the high voltage module.

以下引用自他的文章 (原文链接 https://0x7d.com/2017/nixie-tube-clock/#Nixie_Power_Supply):“If you are looking for a good off-the-shelf power supply, YanZeyuan’s NCH6100HV is a pretty good choice. As a word of warning, don’t get the cheaper knockoffs as they use inferior components. The fake one I got was capable of sourcing ~200V but could only source 8mA compared to the 40mA from the NCH6100HV. The NCH8200HV is also a good choice if you are looking for a smaller high efficiency (86% @ 17mm × 18mm!) power supply.”

译文：如果你需要一款(辉光管)的电源，严泽远的NCH6100HV是个非常好的选择。不过需要注意，不要买市面上的假货。我买过的假货可以提供~200V的电压，但是只能提供8mA的电流，而严泽远的NCH6100HV可以提供40mA电流！如果你正在寻找体积更小、效率更高的辉光管高压电源，NCH8200HV也是一个很好的选择，他可以做到高达86%的转换效率，体积只有17mm x 18mm。

随着越来越多的朋友了解辉光管，不少爱好者们也开始尝试设计自己的辉光钟作品，无论在功能与外形创意上如何千变万化，要想让这种濒临灭绝的古老器件焕发光彩，则必须提供给她170v的工作电压。
当然，升压方案已不是什么难题，无论是众所周知的MC34063A升压方案还是传统的NE555的升压方案，都能轻松的达到目的。不过为了满足更多创意需求，更小的体积、更低的输入电压、更强的负载能力和更高的转换效率成为了大家所追求的目标；这一次，在继NCH6100HV升压模块之后，我又一次把升压电路封装成高压升压模块，只不过这次她体积更小、输入电压更低（可以轻松使用锂电池供电）、负载能力更强并且转换效率更高，她就是NCH820HV辉光管高压升压模块。

With more and more friends know the Nixie tube, many enthusiasts have begun to try to design their own Nixie clocks, no matter how the function and apperance changes, if you want to make this endangered old device glow, you need  a high voltage power supply.
Now, the DC-DC boost converter is no longer a problem, whether it’s well-known MC34063A booster or the traditional NE555 booster circuit, all can easily to drive Nixie tubes. But in order to meet more creative requirements, smaller size, lower input voltage, more load capacity and higher efficiency has become the goal we have pursued. This time, after the NCH6100HV boost module, I packaged a new high-voltage DC-DC boost converter again, but this time it’s smaller, lower input voltage (easily to power it with lithium battery), the load capacity is stronger and efficiency is higher, it’s the NCH8200HV Nixie power supply.

NCH8200HV高压升压模块是一款新型的专为辉光管设计的高效率直流至直流变换器，输入电压范围2.5-15v，输出电压170v，特别适合于锂电池供电或者USB供电方式，整个模块体积小巧，转换效率高，发热量低，使用方便，并且脚间距兼容2.54mm孔距的面包板，实物照片：

The NCH8200HV Nixie power supply is a new high-efficiency DC-DC converter designed for Nixie tubes, the input voltage range is 2.5-15v and the output voltage is 170v, it’s especially suitable for lithium battery or USB power supply, it’s compact, high efficiency, low heat, easy to use, and the pin pitch compatible 2.54mm bread board.
