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 (

In any operating system, distribution losses are a significant factor in overall system efficiency at every level. In the case of telecom central office applications, traditional 48Vdc systems become very expensive to install (due to increased copper cost and weight) and run (due to I2R loss) while in large da
