Here’s how a 3D EM simulation can be used to accurately gauge gate-driver trace inductance. JOHN RICE | TEXAS INSTRUMENTS INC. HIGH ELECTRON MOBILITY TRANSISTORS (HEMTS) were first introduced in the early 1980s and are touted for their exceptional switching qualities. These so-called heterojunction, field effect transistors (FETs) were originally developed for high-frequency RF power […]

More packaging options for motor drive power modules
STMicroelectronics has extended its SLLIMM nano series of Intelligent Power Modules (IPMs) for motor drives with more package options that help minimize overall size and complexity, extra integrated features, and greater efficiency leveraging the latest-generation 500V MOSFETs. With a current rating of 1A or 2A, the new IPMs target applications up to 100 Watts, such […]
eGaN FET and IC applications center to open in Virginia
Efficient Power Conversion Corp.(EPC), a supplier of eGaN FETs, says it will open an Applications Center in Blacksburg, Va. This center will support research and development for the applications of enhancement-mode gallium nitride transistors and ICs. GaN technology has enabled emerging applications such as wireless power transfer, LiDAR for autonomous vehicles, and envelope tracking for […]
Current Circuit: MOSFET bridge rectifier with low forward drop
by “Crutschow“, forum member on Electro-Tech-Online.com The lowest input to output voltage drop you can get with a standard bridge rectifier is nearly a volt through the two conducting diodes for each half cycle, even with Schottky diodes in the bridge. That can generate a dissipation of about a watt per amp of output current in […]
700-V MOSFETs target quasi resonant flyback topologies
Infineon Technologies AG developed the new 700 V CoolMOS™ P7 family to serve today’s and tomorrow’s trends in quasi-resonant flyback topologies. These new MOSFETs offer unmatched performance improvements compared to currently used superjunction technologies. Soft switching topologies like smart phone and tablet chargers but also notebook adapters profit from this advantage. Additionally, the new CoolMOS supports fast […]
SiC MOSFETs deliver 196 A for EV drivetrain uses
Wolfspeed, a Cree Company and a leader in silicon carbide (SiC) power products, has introduced a 900V, 10mΩ MOSFET rated for 196 A of continuous drain current at a case temperature of 25°C. This device enables the reduction of EV drive-train inverter losses by 78 percent based on EPA combined city/highway mileage standards. This efficiency […]
