Let’s say that you’re trying to drive a few Nixie clock tubes, or you want to make a strobe light. A variable high voltage DC power supply from 50-200+ volts may be required. Transformers are terrific, but difficult to find the right one and a pain to wind. Why not use a boost converter? They’re easy and don’t necessarily require a guru for basic operation. This guide is meant for the individual who wants to build a simple boost converter, and may need refreshing on the theory. It will also help determine what parts will be required.
