This year was the first post-covid APEC, attracting 6,100 visitors (up from 5,800 in 2019). Report by Caroline Hayes. Integration and miniaturisation were key themes and Silanna Semiconductor introduced the SZ1200 to its CO2 Smart Power family of AC-DC and DC-DC converters. The active clamp flyback controller integrates adaptive digital PWM control with a 700V primary GaN fet, X capacitor ...
Advanced Energy Industries is showing its NP08 4kW ac-dc power supply at APEC in Long Beach this week. The first member of its NeoPower (NP) family of configurable multi-output supplies, it has eight output slots for configuration and 18W/inch3 claimed density for ~283 x 203 x 64mm chassis. Input is single-phase 90 – 132Vac and 180 – 264Vac. “NP08 also ...
ITG Electronics will feature 600Vac common-mode chokes at APEC in February, which offer “higher voltage ratings and more robust hipot Isolation between two windings – the products address increasing demand for industrial, under-the-hood inverter applications”, it said. That hipot isolation is 2,500Vac. There are two series: C301306H measuring 44 x 48 x 34mm, and C301369H at 34 x 35 x 26mm. ...
Power Integrations is aiming at industrial and automotive power supplies up to 100W, by building 900V GaN transistors into its InnoSwitch3 fly-back switcher family – something it announced at APEC in Florida. Previously 750V was the highest rating amongst the GaN members of this family. There are two product lines now with 900V gallium nitride options: The AEC-Q100-qualified InnoSwitch3-AQ family ...
Microchip has unveiled a 3.3kV silicon carbide mosfet and mating Schottky diodes. MSC025SMA330 is the 25mΩ mosfet in a four-lead TO-247 package, and MSC090SDA330 is the 90A diode in a similar two-lead ‘T-Max’ package. Both are also available in die form. Further data on the mosfet is sadly not public at the moment, but the diode data sheet is available and shows ...
Onsemi has announced an interleaved, two-phase power factor correction controller for ‘bridge-less’ totem pole topologies from 350W to several kW of 90 – 265Vac mains input. Interleaving parallels multiple small stages, allowing more numerous smaller component to be used, distributing heat, reducing ripple amplitude and potentially lowering EMI. “Also, interleaving extends the power range of critical conduction mode that is ...
GaN Systems is claiming “the world’s smallest 65W and 100W GaN chargers” at APEC this week. Made with power design company Rompower, the 65W charger is 30.5 x 35 x 46.6mm (21.4W/in3). Peak efficiency is ~94.5% (115Vac) or ~95% (230Vac). For the 100W unit, GaN Systems has given four dimensions: 28.6 x 44 x 35 x 67mm (Electronics Weekly has asked ...
On Semiconductor will be showing enhancements to its cloud-based power development tool, branded Strata, which it announced at CES earlier this year. Search capabilities have been improved, and there is a carousel-style menu that allows compatible devices and boards to be selected, said the firm: “Engineers are able to narrow down viable component and systems solutions options and be confident ...
Fairchild is revealing a 100V mosfet with maximum on-resistance of 4.2mΩ at 10Vgs and Id=44A, or 12mΩ at 6Vgs and Id=22A. Called FDMS86181, it is a ‘shielded gate’ mofet. “FDMS86181 is the first part in a new generation of mosfets and it delivers substantial improvements in efficiency, reduced voltage ringing and electromagnetic interference for power supplies, motor drives and other applications requiring ...
Canadian gallium nitride transistor firm GaN Systems has announced top-side cooled power devices at the Applied Power Electronics Conference in North Carolina, which means they can be cooled with a normal heatsink or fan. “These are conventional techniques that are well-understood and familiar to design engineers who may be unfamiliar with using GaN devices or using them for the first ...
