Higher density, low-power SMPS designs require high voltage MOSFETs in a growing number. Infineon Technologies AG announces new member of its CoolMOS P7 family, the 950 V CoolMOS P7 Superjunction MOSFET. It meets even the most rigorous design requirements: for lighting, smart meter, mobile charger, notebook adapter, AUX power supply and industrial SMPS applications. This […]
Next-gen 650V MOSFETs target data centers, UPS, industrial applications
Toshiba Electronic Devices & Storage Corporation has launched a new series of next-generation 650V power MOSFETs that are intended for use in server power supplies in data centers, solar (PV) power conditioners, uninterruptible power systems (UPS) and other industrial applications. The first device in the DTMOS VI series is the TK040N65Z, a 650V device that […]
The benefits of silicon carbide in dc/dc converters
Adil Salman from Wolfspeed recently shot a video with us covering a silicon carbide charging circuit demonstration. The charger used Wolfspeed SiC MOSFETs. It had two stages. One is a PFC (power factor correction) stage, the other is an LLC converter stage. If you were to try building a similar charger with silicon IGBTs, you […]
Power Electronics Top Talks in July on EDABoard.com forums
Peer-to-peer, engineer-to-engineer questions and answers from the EDABoard.com engineering community around power electronics. Click the “Read more” link and follow the entire conversation and maybe add your two cents by logging in to EDAboard.com MOSFET running at high temperature – In our 180W LED driver, the SPB07N60C3 MOSFET was running with degrees measured on its tab. […]
1,000 A to a welder through a MOSFET
Rehan Tahir from Infineon recently filmed a video with us covering a cool demonstration that develops a thousand amps for a welder. The point was to highlight an Infineon 1 kA board that actually targets applications powering the GPUs and next-generation CPUs that will need a thousand amps or more. The demo uses Infineon power […]
Graphics-intensive apps get more juice from GaN dc/dc converters
Alex Lidow from EPC recently did a short video with us covering a brand new GaN-DC/DC converter that’s super small and efficient. Lidow says EPC has been working to improve GaN-based dc/dc conversion for about eight years. They had to overcome a lot of barriers to do so because when they first started, there were […]
Eval kits help design silicon-carbide power circuits
There’s a lot of benefits that come with silicon carbide semiconductor devices. Increased power density, increased efficiency, lower form factor, simpler designs, simpler thermal management, are all examples of the benefits. But along with the things that silicon carbide enables, there’s also some side effects that make them hard to control, and if they’re not […]
MOSFET gate driver in 5.0mm x 5.0mm for automotive 3-phase motors
Toshiba Electronic Devices & Storage Corporation announces the availability of a new compact power MOSFET gate driver intelligent power device (IPD) for automotive 3-phase brushless motors. The device is intended for use in automotive motor drive applications, such as 12V electronic power steering (EPS), oil/ water pumps, fan motors and electric turbochargers. Toshiba’s IPD products […]
MOSFET driver delivers 5V to 20V DC from an AC supply
Diodes Incorporated announced the APR346 secondary side synchronous rectification MOSFET driver, providing increased efficiency for off-line power adapters delivering 5V to 20V DC from an AC supply. Designed to operate in Continuous Conduction Mode (CCM), Discontinuous Conduction Mode (DCM) and Quasi-Resonant mode (QR), the APR346 is used to drive an external MOSFET to deliver the benefits […]
600-V MOSFET combined with 650-V Schottky diode in top-side cooled surface-mount package
Increasing complexity of end products is challenging the design parameters for high power supplies: these require higher power and more efficiency in an even smaller space. Semiconductor devices are essential to the operation and performance of modern switched mode power supplies (SMPS). Over the last years, a trend towards surface mount devices (SMD) has been emerging.
