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

Manufacturing Bits: June 7


High-voltage superjunction SiC devices The University of Warwick and Cambridge Microelectronics have presented a paper on the latest effort to develop of a new type silicon carbide (SiC) power device called a SiC superjunction Schottky diode. Researchers have simulated and optimized the development of 4H-SiC superjunction Schottky diodes at a voltage class of 1700 volts, aiming for breakdow... » read more

Automotive IC Shortage Drags On


The current automotive semiconductor shortages won’t end anytime soon. When the COVID-19 pandemic hit in early 2020, it wreaked havoc on the worldwide supply chain, but it especially caught automakers flat-footed. When the auto OEMs canceled chip orders during a roughly eight-week period of plant shutdowns, they later found their supplies of critical ICs had evaporated. To make it an ev... » read more

Going Vertical With GaN Devices


Gallium nitride has long been on the horizon for a variety of uses in semiconductors, but implementing this on a commercial scale has been relatively slow due to a variety of technical hurdles. That may be about to change. The wide bandgap of GaN makes it particularly attractive material for power conversion applications. Still, actually realizing its benefits in commercial devices has been ... » read more

SiC MOSFETs In The Landscape Of Modern Power Devices


Over the years, low losses possible by high breakdown field made silicon carbide (SiC) MOSFETs extremely popular amongst engineers. At present, they are mostly used in areas where IGBTs (Insulated Gate Bipolar Transistors) have been the prevailing component of choice before. But which role do SiC MOSFETs play in today’s landscape of power devices? With SiC MOSFETs (Metal-Oxide-Semicond... » read more

IC Materials For Extreme Conditions


The number of materials being researched for chips used in extreme environments, such as landing on the planet Venus, is growing. While GaN has captured much of the attention for power conversion circuits, it's just one of several applications for semiconductors in extreme environments. The high voltage, high temperature, and caustic atmospheres found in many industrial and aerospace environ... » read more
