Revving Up SiC And GaN


Silicon carbide (SiC) and gallium nitride (GaN) are becoming more popular for power electronics, particularly in automotive applications, driving down costs as volumes scale up and increasing the demand for better tools to design, verify, and test these wide-bandgap devices. Both SiC and GaN are proving essential in areas such as battery management in electric vehicles. They can handle much ... » read more

Choosing A Gate Driver For Silicon Carbide MOSFETs


If you are going to use a silicon carbide (SiC) MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) in your next development, you will ask yourself: how do I develop the best gate driver for it? The answer to this question is: identify a suitable gate driver IC based on the peak current and power dissipation requirements of your application and a fitting gate resistor for your SiC... » read more

Inspecting, Testing, And Measuring SiC


Achieving the auto industry's stringent zero defect goals is becoming a big challenge for makers of silicon carbide substrates, which are struggling to achieve sufficient yields and reliability as they migrate from 150mm to 200mm wafers and shift their focus away from pure silicon. SiC is a combination of silicon and harder carbide materials, and it has emerged as a key technology for batter... » read more

The Silicon Carbide Race Begins


The growing adoption of silicon carbide (SiC) for a variety of automotive chips has reached the tipping point where most chipmakers now consider it a relatively safe bet, setting off a scramble to stake a claim and push this wide-bandgap technology into the mainstream.

Gearing Up For Next-Gen Power Semis


After years in R&D, several vendors are moving closer to shipping power semiconductors and other products based on next-generation wide-bandgap technologies. These devices leverage the properties of new materials, such as aluminum nitride, diamond, and gallium oxide, and they are also utilized in different structures, such as vertical gallium-nitride power devices. But while many of thes... » read more

Short-Circuit Ruggedness In SiC MOSFETs


Trench-based silicon carbide power MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) represent a dramatic improvement in the Figure of Merit (FOM) values of power conversion switching devices. As a result, outstanding system performance is achieved, enabling higher efficiency, power density, and reduced system cost for many applications. Today, for major target applications for S... » read more

Problems In The Power Grid


The gap is widening between power availability and peak demand. Ritesh Tyagi, head of innovation and growth strategy at Infineon Technologies, talks about what needs to be done to fix the power grid, particularly as more cars are electrified and more electronic devices are mobile. While there currently is a surplus in power being generated on a macro level in the United States, for example, it�... » read more

SiC And Industrial Servos: A Perfect Match


The automation engineers of the 1960s would look with envy at the servo technology in use today. Small, precise, and, above all, electric, they are a reflection of the compactness of the semiconductor control, sensor, and power technology we have available today. Today’s biggest challenge remains the cabling between the servo and its controller. Notoriously expensive, due to having to withsta... » read more

Power, Performance — Avionics Designers Want It All


Not long ago, the prevailing philosophy among chip designers for aviation systems could be summed up as, “I feel the need — the need for speed.” Today, aviation’s top guns have pulled back on the throttle a bit. There’s a more nuanced discussion balancing the need for performance versus power, with other factors coming into consideration such as safety, security certifications and ove... » read more
