“Major carmakers and automotive Tier-1s are now committing to silicon-carbide technology for future product development to leverage its higher aggregate efficiency compared to standard silicon in a wide range of operating scenarios,” said Mario Aleo, Group Vice President and General Manager, Power Transistor Division, STMicroelectronics. The smaller SiC diode and transistor structures present lower internal resistance and respond more quickly than standard silicon devices, which minimize energy losses and allow associated components to be smaller, saving even more size and weight. Silicon carbide is a newer, wide-bandgap technology that allows smaller device geometries capable of operating well above the 400V range of today’s electric and hybrid drivetrains. Today’s power modules typically rely on standard silicon diodes and Insulated Gate Bipolar Transistors (IGBTs). These include the traction inverter, OBC (On-Board Charger), and auxiliary DC-DC converter. A leader in silicon carbide, ST is among the first to present new-generation rectifiers and MOSFETs for high-voltage power modules and discrete solutions addressing all the vehicle’s main electrical blocks. In EVs and hybrids, where better electrical efficiency means greater mileage, ST’s latest silicon-carbide (SiC) technology enables auto makers to create vehicles that travel further, recharge faster, and fit better into owners’ lives. STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronic applications, has announced advanced high-efficiency power semiconductors for Hybrid and Electric Vehicles (EVs) with a timetable for qualification to the automotive quality standard AEC-Q101. AEC-Q101 qualification program to complete in early 2017, ready for new OEM product launches.Advanced 6-inch wafer capability and process to bring superior SiC offer to carmakers and automotive suppliers.Complete set of devices allows full conversion of auto power modules to silicon carbide (SiC) for greater vehicle range, convenience, and reliability.
