- Melexis launched the MLX91299 RC snubber to improve efficiency in EV power electronics.
- The device can reduce switching losses by up to 50 percent in Silicon Carbide modules.
On March 5, Melexis introduced a new protective device aimed at improving efficiency in modern power electronics used in electric mobility. The launch marks the start of a broader product line designed to stabilize high-speed switching systems and reduce electrical stress in advanced power modules. The first device, the MLX91299, targets performance challenges emerging in Silicon Carbide traction inverter systems.
Protective circuit designed for SiC power modules
The Melexis MLX91299 RC snubber integrates a silicon based resistor capacitor circuit that suppresses high frequency oscillations and voltage transients created during rapid switching of Silicon Carbide devices. Early measurements show switching losses can fall by up to 50 percent, reducing heat and improving energy transfer from battery to wheels. This efficiency gain supports longer electric vehicle driving range and reliability.
