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 (

Figure 1: Comparison of Superjunction transistor, SiC MOSFET, and GaN HEMT

The commercial availability of Superjunction transistors 20 years ago, challenged and finally proved wrong the limitations of conventional silicon-based transistors with respect to on-state resistance. What was regarded as revolutionary at that time is standard today. Today there is not a single transistor from 25

Are you SiC of Silicon? – Part 5

Anup Bhalla, Vice President Engineering, UnitedSiC

Ultra-High Voltage SiC and Supercascodes New applications are emerging that require high voltage switch technology which is significantly lower in balance-of-system costs and operating losses than silicon IGBT and IGCT technology. This spans a wide range from solid state transformers, MW motor drives, to smart
