Designing for reliability in high voltage applications

Posted on 28 May 2017
High voltage design and manufacturing comes with an additional set of disciplines that must be applied in order to produce products with excellent long term reliability, often in harsh environments. As high voltage power supplies become increasingly compact and miniaturized, mastering these disciplines is essential to ensure long term and trouble-free operation in the field. Failure to properly apply these design and manufacturing principles can result in real-world MTBF well below design expectations. In school, we were taught that materials were either conductors or insulators. Air was said to be an insulator. However, lightning proves that air is not always an insulator. Welcome to the world of high voltage!

Removing heat from sealed enclosures

Demand for power supplies that can withstand harsh environmental conditions does not only come from defense applications. Telecommunications base stations and infrastructure for the smart electricity grid of the future place steep demands on power supplies. These systems are subject to the extremes of temperature, dust and humidity.
