“If you look where silicon carbide is going, it started at 1,200 volts, which is far from where silicon is competitive. Now, it’s trying to work it’s way down and trying to get market share in the 900- and 600-volt range. “If you go to 600 volts, and you look at everything
Effect of different silicon sources on rattan-based silicon …
Rattan-based silicon carbide (R-SiC) ceramics, R-SiCSiO2 and R-SiCSi, were successfully prepared from silica (SiO2) sol and silicon (Si) powder, respectively. The rattan powder was impregnated, respectively, with SiO2 sol at aient temperature and liquid melt-Si at high temperature. This was followed by one-step direct pyrolysis at 1500 °C under an argon (Ar) atmosphere. The final SiC

GaN Enabling a Revolution in Charger Design | EE Times
GaN Technology (shown in red) is able to reduce the total switching loss for a power switch operating at offline flyback voltages (switch rating 600–750 V). (Click on image to view larger version.) The change in switching efficiency created by the introduction of the GaN switch also dramatically reduces the thermal challenges, leading to a further miniaturization of chargers.
