Exploring the frontiers of GaN power devices
GaN power semiconductors allow for innovation in the harsh radiation environments of space applications, says David Reusch. Improvements to power semiconductors are vital to overall system performance. Advances in design techniques and improved component technologies enable engineers to achieve higher efficiency and higher power density while maintaining high reliability and minimising cost. Gallium nitride (GaN) power semiconductors offer designers of ...
1.2kV dual gate driver for SiC mosfets
Microchip has announced a 1,200V dual digital gate driver for electric transport. Called AgileSwitch 2ASC-12A2HP, “the gate driver provides multiple levels of control and a higher level of protection for silicon carbide mosfet-based power systems,” according to the company. “Key performance attributes include the ability to dampen drain-source voltage overshoots and slash switching losses”. The driver can source and source up ...
Intersolar: Delta to show 3-phase 250kW 1.5kV solar inverter
Delta has announced a three-phase 250kW solar string inverter with an input range of 550 to 1,500Vdc “specially designed for huge ground-mounted photovoltaic plants in the upper megawatt range”, according to the company. “Features such as anti-PID and pro-electroluminescence detect problems with PV modules.” Called M250HV, up to 30 dc strings can be connected to its 12 max power point trackers, ...
260W mains PSU for IT equipment can run at 170W with no fans

Infineon opens thin wafer power fab
Earlier today, Infineon opened its fab for power electronics on 300mm thin wafers at its Villach site in Austria. At €1.6 billion, the investment made by the semiconductor group represents one of the largest such projects in the microelectronics sector in Europe. The Villach site is one of the world’s most modern fabs and was opened by Infineon CEO Reinhard ...
Flexy-to-PCB connector offers 20 x 1A connections for automotive
Panasonic has introduced 20 pin version of its automotive-grade flexible printed circuit (FPC) to rigid-PCB connector. Called CF2, the two-part connector has two rows of 10 pins (custom arrangements possible) and is rated for 125°C, 44m/s2 (20 – 200Hz vibration and 981m/s2 (6ms) shock. Capacity is 1A/pin and 50Vdc – it builds upon the early single-row CF1 types (4, 6 ...
Nexperia SMD power package accepted by automotive Tier-1
Nexperia’s CFP15B clip-bond surface-mount power package has passed automotive board-level reliability (BLR) testing by a “leading”, said the company, tier-1 supplier. Initially, it will be used in an engine control unit. “BLR verification is an important milestone,” said Nexperia product manager Guido Söhrn. “CFP15B represents the latest generation of thermally-enhanced thin surface-mount devices.
