Advantages of capless LDOs

Power management of battery powered electronic devices is becoming increasingly more important for the present and future microelectronics industry.

Power electronics in automotive applications

This whitepaper presents a review of power electronics systems in electric vehicles with emphasis on the power train system. It also addresses the high temperature requirements in the power train system and the advances in power electronics to handle them.

FPGA based control for EV and hybrid EV power electronics

This whitepaper from Altera describes the benefits of using fpga based control in a hybrid electric vehicle or electric vehicle drive system comprised of a variable voltage control or bi-directional dc/dc converter, three phase inverters and interior permanent magnet.

Optimising operating life for led based light bulbs

The replacement of incandescent lighting mandated by the largest countries around the world is powering a paradigm shift to solid state lighting. But without the right precautions the lofty promise of nearly 25 years without changing a light bulb may fall short.

Advanced power devices for slimmer PSUs

As power supplies for high volume products such as tvs and computers are required to meet ever tougher demands on form factor, efficiency and cost, power supply controllers must integrate more features in order to increase efficiency while minimising component count, pcb size, complexity and bom costs.

Efficiency standards for external power supplies

OEMs who design external power supplies into their products must continue to monitor the latest regulations to ensure that they are in compliance in each region their product is sold. The goal of this article is to provide an up to date summary of the most current regulations worldwide.

Mastering power modules - The advantages over discrete solutions

With the strong upsurge in the need for power electronics in applications such as solar, wind, industrial drives and UPS, system developers are becoming increasingly aware that the selection of the power devices for these often remotely-sited applications is critical. Such systems require the highest reliability and efficiency to minimise operating costs and build industry integrity for the developer.

Digital techniques in power conversion

The concept of "digital power" has received significant attention and promotion in the past few years, from both semiconductor suppliers and power supply manufacturers. There is a need to explain the concepts of digital power; explore the advantages and tradeoffs of digital techniques compared to analogue approaches; discuss some of the standardisation directions; and explore the possibilities for digital power.

Is digital power moving forward?

It is now several years since commercial products with 'added digital performance' aiming to revolutionise the power industry have been around in the marketplace. At a time when energy efficiency and power consumption are becoming more strategic than ever, the debate around how "digital power" will change the face of the world has never been so intense. Energised by the high marketing buzz surrounding 'the new power revolution', thousand of papers have often strongly expressed the details and benefits of implementing such technology. However, a certain market perception gives the feeling that behind the noise generated by the media, digital power seems not to have moved as fast as expected. Wrong perception or reality?

From digital confusion to digital conversion

It is now several years since commercial products with 'added digital performance' aiming to revolutionise the on-board power industry have been around in the marketplace. The debate around how such products will change the face of the world has never been so intense, resulting in a certain kind of confusion.

Digital DC/DC converter family integrates PMBUS connectivity

Able to work with any type of power converter, PMBus is a major success story. Its simple SMBus-based two-wire hardware interface is similar to and generally compatible with I2C, while the improved signaling protocols assure greater robustness. As a result, system designers can easily implement power management strategies that range from voltage sequencing or multi-voltage logic devices to monitoring and controlling entire systems using a uniform approach that has minimal impact upon resources.

Digital DC/DC converter benefits in MicroTCA power modules

Micro Telecommunications Computing Architecture (MicroTCA) is a relatively new architectural specification for Information and Communications Technology (ICT) and industrial equipment intended for relatively small, low power applications where it can be more cost effective than other architectures. The key power assembly in MicroTCA is called the 'MicroTCA power module' , which, by its own definition has to deliver and secure the power required by Advanced Mezzanine Cards and other accessories that plug-into the MicroTCA enclosure.

Batteries worldwide celebrate the arrival of the world's most energy friendly microcontrollers

The explosion in use of battery operated electronics is followed by the need for the battery to last longer for convenience, environmental and cost reasons. At the same time, applications become more and more complex and demand higher performance of the microcontroller, making the challenge of designing systems for low power even more difficult. This white paper looks at Energy Micro's EFM32 microcontroller family, which it says has an energy consumption many times lower than any other microcontroller family today, whether you benchmark with leading 8, 16 or 32 bit microcontrollers.

3E-Enhanced performance, Energy management and increased End-user value with digital POL regulators

Ericsson Power Modules' new digital POL (point-of-load) regulators establish an innovative approach to reach the goals of end-user value, flexibility and system performance. These new power supply products contain several unique concepts and features spanning the disciplines of mechanical packaging, electrical design, control loop algorithms, power system architecture, power and energy management tools and logistics during system manufacturing and field support.
