Power

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.

Buck controller eliminates intermediate power conversion

The ISL8117, from Intersil, is a 60V synchronous step-down PWM buck controller that can bypass the intermediate step-down conversion stage traditionally employed in industrial applications. Its low duty cycle (40ns minimum on time) enables the direct step-down conversion from 48V to a 1V point-of-load. This makes it possible for designers to reduce system complexity and solution cost in industrial, factory automation, medical and communications infrastructure applications.

HV-IPD for sine-wave motor control

Toshiba has launched the TPD4204F, a high voltage intelligent power device that enables the sine-wave control of brushless DC electric motors. The device can be used in a range of low power industrial fans and pumps, as well as in white goods such as washing machines, dishwashers and fan units.

Power management chipset helps optimise dead time

Texas Instruments has introduced a power management chipset with intelligent digital control and a body-diode sensing feature to optimise secondary-side synchronous rectification in next-generation AC/DC and isolated DC/DC power supplies.

Navigate through digital power system design

Version 5.2 of Intersil's PowerNavigator software is now available. The package, which can be downloaded free of charge, helps system designers to configure, validate and monitor systems featuring the company's PMBus enabled digital power products.

Wide input and noise immunity DC/DC converters

The DDC15 and DDC30 series of low profile 15W and 30W DIN rail format DC-DC converters have been announced by XP Power. The single output converters accept inputs in the range from 9 to 36V DC, suiting a 12 or 24V DC nominal input. The range is designed to offer additional voltages in DIN rail power systems, provide isolated outputs and noise immunity or support battery powered or battery backed applications.

Simplifying digital power conversion

Helping designers to maximise the advantages of digital power conversion, including high efficiency under load conditions, enhanced safety, rich diagnostics and convenient network connectivity, STMicroelectronics has released the STNRG range of digital controllers.

Reliable and compact inverter

Infineon has launched its latest Intelligent Power Module (IPM). The MIPAQ Pro provides a range of scalable and compact inverter designs to be implemented in wind, solar and industrial drive applications.

Packaging design reduces switching loss

Four products in Toshiba's DTMOS IV-H range – the TK25Z60X, TK31Z60X, TK39Z60X and TK62Z60X, all of which feature Vdss of 600V with Rds(on) values as low as 40mohm – have been released in a four pin TO-247 package.

Industry's fastest 16bit A/D converter

Texas Instruments has announced the ADS54J60, which is claimed to be the industry's first 16bit 1Gsample/s A/D converter and the first to achieve a signal to noise ratio of more than 70dBFS at 1Gsample/s. The device is suited for use in defence and aerospace, test and measurement, and communication infrastructure applications.

3000W power supply for mission critical applications

CUI has introduced a 3000W front end AC/DC power supply for mission critical N+1 redundant applications. The hot-swappable PSE-3000-48, which provides an output of 48V DC with a typical efficiency of 94% at 50% load, is suited for telecom, server and networking applications where energy reduction is a concern.

Synchronous buck switching regulator

The ISL8002B synchronous buck switching regulator from Intersil delivers an output of up to 2A from an input supply ranging from 2.7V to 5.5V. With a switching frequency of 2MHz, the part is said to offer superior transient response, while key features such as programmable soft start and output tracking and sequencing of FPGAs and microprocessors, increase system reliability for point of load conversion.

New Li-ion battery charger from TI

Texas Instruments (TI) has produced a Li-ion battery charger that facilitates faster and cooler charging by combining narrow-voltage DC/DC power path management with their proprietary MaxCharge technology to support input voltages up to 14V while providing charge current up to 5A.

Efficient 600W DC-DC converters

Artesyn Embedded Technologies has launched the ADQ600 series, a range of 600W quarter-brick isolated DC-DC converters with high efficiency and thermal performance making them suitable for use in telecom and data center equipment.

Toshiba launches 4500V 1200A IEGT module

The MG1200GXH1US61 PMI has been launched by Toshiba Electronics Europe. It is a high-current 4500V, 1200A power module for use in rail traction, industrial motor control, renewable energy systems and electricity transmission and distribution applications.

Converter with high power capability

Ericsson has introduced a DC/DC converter module based on its proprietary Hybrid Regulated Ratio (HRR) technology. The PKM4817LNH has been optimised for parallel operation to power 2200W boards in extreme-data-demand applications in the datacom industry.

eGaN power transistors cost less than silicon

According to Efficient Power Conversion, price has been the last barrier to the widespread adoption of GaN transistors as a replacement for silicon MOSFETs. But it claims this barrier has fallen with the introduction of the 60V EPC2035 and 100V EPC2036, which are not only said to be cheaper than silicon equivalents, but also to provide better performance.

Converter offers longer battery run times

ams has introduced a 1A synchronous buck converter with a wide input voltage range, high efficiency and low stand-by current. The device is said to suit designs powered by a single cell lithium-ion battery.

Delivering usable power at high temperatures

Artesyn Embedded Technologies has unveiled a new family of fanless, conduction-cooled AC-DC power supplies. The LCC600 series has been designed to deliver their full 600 Watt power output across a wide operating temperature range of minus 40 to 85 degrees Celsius.
