Silicon Carbide and its Importance in Apex Products
Silicon Carbide Technology
Silicon Carbide (SiC) is a compound material composed of silicon (Si) and carbon (C) that is utilized in the semiconductor industry to gain an efficiency advantage over traditional silicon devices. The physical bond of Silicon Carbide is extremely durable which gives the material increased thermal stability; the wide band gap and broad thermal capabilities allow for an expanded temperature range compared to traditional silicon. Some of the benefits that give Silicon Carbide products the advantage over typical materials can be:
Excellent switching characteristics over wide temperature ranges
Reduced power loss compared to silicon or IGBT solutions
Lower application/system operating cost
Increased power delivered
Broad operational temperature range
Increased voltage supplies
Apex Microtechnology offers a family of products that utilize Silicon Carbide MOSFET technology, this includes the SA310 and SA110 as well as products currently in development. The value of using Silicon Carbide in Apex power modules is realized in several areas:
Excellent switching performance, which allows for the lowest possible switching losses
Integrated gate drive, which can allow for simplicity of use and reduced development costs
Compact packaging to minimize device footprint and maximize power density
The SA310 is a fully integrated three-phase power module designed primarily to drive Brushless DC (BLDC) and Permanent Magnet Synchronous (PMSM) motors or DC/AC converters. The module uses Silicon Carbide MOSFET technology to improve efficiency over other devices in its class.
The SA110 is a high current, high voltage half H-bridge integrated power module that uses Silicon Carbide (SiC) MOSFETs with integrated gate drive. The SA110 is ideal for applications where focus is on thermal performance, high efficiency, and having a compact design.
