Technology Spotlight Find out more
Multi-level Turn-off
Optimizes the entire turn-off process, cutting turn-off delay while suppressing voltage peaks, so modules switch faster.

Miller Clamping
Holds the gate firmly off during fast, high-voltage switching transients, so the Miller effect can't turn the IGBT on by mistake.
Learn more
Short-circuit
SiC devices tolerate a short circuit for far less time than IGBTs, so protection must respond quickly and robustly.
Learn more
Multi-parallel
Solves the circulating current problem when SiC modules are paralleled, enabling higher output power.
