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 (
