by Rudye McGlothlin, Silicon Laboratories Although solar cells were invented some 60 years ago, solar technology is just now becoming a mainstay energy source for utility operators as they move to offload fossil fuels and incorporate more renewable energy sources. Despite a slowdown in 2018 after a reduction in solar feed-in tariffs in several countries, […]

SiC-based inverter boosts EV charging efficiency with 800-V operation
Delphi Technologies is the first in the industry with volume production of an 800 V silicon carbide (SiC) inverter, one of the key components of highly efficient next-generation electric and hybrid vehicles. The new inverter enables electrical systems up to 800 volts, significantly extending electric vehicle (EV) range and halving charging times compared with today’s […]
High-efficiency inverters target PV, energy storage apps
Compared with traditional 3-level neutral-point-clamped topologies, the advanced neutral-point-clamped (ANPC) inverter design supports an even loss distribution between semiconductor devices. Infineon Technologies AG utilizes the ANPC topology for its hybrid SiC and IGBT power module EasyPACK 2B in the 1200 V family. Optimizing for sweet spot losses of the CoolSiC MOSFET and the TRENCHSTOP IGBT4 […]
