Power electronics is a key element in the world of electronic design and engineering and electronic engineers need to have a thorough understanding of this area if they’re going to create successful products.

In this section, New Electronics keeps designers up to date with the latest developments in the power electronics market – everything from DC/DC converters to IGBTs to battery technology. In fact, New Electronics covers any power product that can go on a PCB.

First SMARC 2.0 module

Congatec has unveiled its first credit card sized modules for the new SMARC 2.0 specification. They are based on the newly released 14nm Intel Atom, Celeron and Pentium processors (code named Apollo Lake).

Artesyn announces 550W CRPS server power supply

A 550W server power supply has been launched by Artesyn Embedded Technologies which is said to follow the Intel Common Redundant Power Supply (CRPS) specification and which is designed for hyper-converged compute, networking and storage infrastructure in enterprise IT and cloud environments.

Smallest 40W AC/DC open frame power supply launched

The ECF40 series from XP Power consists of single output 40W compact AC/DC power supplies. These open frame convection-cooled units are said to be capable of delivering 40W in temperatures of up to 50°C without the need for any external forced air flow.

Artesyn announces 550 Watt CRPS server power supply

Artesyn Embedded Technologies has launched a 550 watt server power supply following the Intel Common Redundant Power Supply (CRPS) specification, which is designed for hyper-converged compute, networking and storage infrastructure in enterprise IT and cloud environments.

DC/DC converters for surface mount applications

Three ranges of surface mount (SMD) DC/DC converters rated at 1, 3 and 6W of output power with single and dual outputs have been unveiled by XP Power. According to the company, the converters offer higher efficiency and extended operating temperature range when compared to existing models.

40V n-channel devices added to MOSFET family

Two n-channel devices have been added to Toshiba Electronics Europe’s U-MOS IX-H family of high-efficiency, high-speed switching MOSFETs. The TK3R1E04PL and TK3R1A04PL are said to help designers improve performance and reduce power consumption in power supply applications such as DC/DC converters and the secondary side circuits of SMPS AC/DC power supplies.

650V integrated half bridge for smaller power adaptors

Dialog Semiconductor has developed a monolithic 650V GaN half bridge which integrates a high side and low side power switch together with drivers, level shifting, protection as well as analogue and logic components. The power device is said to switch at more than 50V/ns.

Fairchild launches SuperFET III MOSFET family

Fairchild Semiconductor has introduced its SuperFET III family of 650V N-channel MOSFETs which are said to meet the higher power density, system efficiency and reliability requirements of the latest telecom, server, electric vehicle (EV) charger and solar products.

Current sensing optocoupler for servo drives and motors

An optically isolated sigma-delta modulator, the Avago ACPL-C799 from Broadcom, claims to convert an analogue input signal into a high-speed data stream with galvanic isolation. It features a low differential input range of ±50mV, allowing designers to reduce power dissipation across a current-sensing shunt resistor in servo drive and motor applications.
