Introduction Today’s switch-mode power supplies (SMPS) are smaller, more efficient, and lower-cost than ever. The key to their performance is the power switch technologies at their heart – but how should designers choose the right material for this and find the best component to meet their needs? While silicon is the most widely-known constituent of semiconductors, a new group of wide bandgap (WBG) materials is increasingly finding its way into applications. One example is gallium nitride (

Designers of solar power—photo-voltaic or PV—generating systems face some of the same problems as their counterparts in any other power-related technology: the need to constantly improve performance, reliability, longevity, and—above all—efficiency. As with any engineering endeavour, improved performance re
