And as an open source hardware design, the complete KiCad schematic, layout, and BOM are available at GitHub for download so you can try it with your next nixie tube project. The explanations of the steps are explained using the open source KiCad PCB layout software, but most PCB layout software will have similar features. As a result, the new “mini” nixie tube power supply footprint was reduced 27% to just 10.5cm^2.
In this blog, I’ll show you two CAD power tools I used to get this done quickly and efficiently. Keeping both constraints satisfied to the very limit would be difficult without computer-aided design (CAD). The high currents require wide PCB traces to minimize losses and keep the efficiency high, and the high voltage of the supply requires large trace-to-trace spacing to avoid voltage breakdown and arcing. 170v) make the challenge of shrinking the PCB footprint by hand a rather time-consuming task. A good question to ask is how much smaller can the power supply get while keeping the same efficiency and layout objectives? The combination of high transistor currents (i.e. The design achieved a footprint size less than 14.5cm^2 and the efficiency was optimized in ( part 2) of the blog.
In a recent blog entry, I introduced a new type of nixie tube power supply that is powered from 5v, Designing a Small Footprint, Low Profile 5v to 170v Nixie Tube Power Supply (Part 1).
