Power Electronics Summit Edited Abstracts

Enabling technology for energy efficiency
Prof. Dr. Leo Lorenz, Senior Director
Infineon Technologies

System integration and high-power density system design of devices and components are behind the progress in power electronic system development and energy efficiency. New system trends are going towards high switching frequency, reducing or eliminating bulky magnetics and capacitances as well as soft switching topologies for higher efficiency and low harmonics.

Attend this presentation to learn about new technologies, advanced device concepts and future system design aspects for the industrial segment. Components to improve the energy efficiency will be discussed in detail.

Is the future of DC-DC conversion analog or digital?
Mansour Izadinia, Vice President, System and Power Management Business Unit
Maxim Integrated Products, Inc.

The power electronics industry has seen much debate about the future of efficient DC-DC conversion. Analog DC-DC conversion has its followers and in recent years digital DC-DC conversion has gained significant traction.

This presentation aims to demystify the future of efficient power design and address the advantages and limitations of the technologies involved. Special focus is on the optimal use of digital power technologies for efficient, reliable power conversion. Not attempting to end the analog vs. digital debate, the speaker seeks to provoke insights and new thoughts about the possibilities of both analog and digital techniques.

Intelligent Load Management: The Final Frontier
Jimmy Shi, Principal Field Applications Engineer Beijing
Martin Xu, Field Applications Manager Shanghai
Microchip Technology Inc.

In our headlong rush toward a more power-efficient tomorrow, we have driven the efficiency of power conversion into the realm of 90-99%. If we want to make any further gains, the only area of design open to engineers lies in the efficiency of the load. The load should only dissipate power when its function is actually required, turning off the rest of the time.

Attend to learn about control techniques that help you intelligently manage system load - turning it off when not required and powering up the system when needed.

Making PC power solutions green
Mike Mui, Senior Director, Regional Marketing, Business Unit Multimarket Semiconductors Greater China
NXP Semiconductors

Energy efficiency and environment protection has become key to consistent development of China's economy and a necessary criterion for end-products made by Chinese manufactures. Further efficiency improvements are expected, not only in absolute values (85+/90+) but also with respect to low-load conditions.

Learn about NXP's "green" insights and get guidelines on designing cost-effective and highly reliable PC power supplies.

Energy-efficient solutions for computing power supplies (ATX)
Hemen Cheng, Global Sales & Marketing Director, Automotive & Power Regulation Group Shenzhen / Shanghai
Andy Williams, Senior Vice President and General Manager, Automotive and Power Regulation Group Beijing
ON Semiconductor

This session introduces the existing U.S. Energy Star regulation and follows it up with an analysis of the power losses at various stages. Main efficiency challenges are highlighted and solutions for different topologies (Forward 2-Switch, Forward Active Clamp, Half Bridge-LLC) are presented along with their benefits, limitations and cost trade-offs versus power. Tips and tricks intended to increase the efficiency at light load will also be shared.

Attend to learn about the challenges and trends ahead, in particular the move to efficiencies beyond 80 percent.

Efficient power supply design
Jerry Yang, Director of Sales, China
Power Integrations, Inc.

Attend to learn the latest in power supply efficiency standards that are in development in the United States and Europe. This presentation explains where the energy losses occur in a power supply-switching loss, conduction loss, loss in diode rectifiers and the transformer due to parasitic inductances and capacitances-and suggests strategies to optimize the efficiency in the general. The presenter also illustrates a high-efficiency notebook adapter circuit using the company's TOP-HX product.

Portable power management IC trends
Uwe Mengelkamp, Director, Portable Power Management
Texas Instruments

Form-factor requirements in today's consumer electronics often require designers to use integrated components in smaller and thinner packages. As designs become more complex, it is important to understand the design issues that may cause noise and thermal challenges, which extend development time.

Attend to find out how today's power ICs combine several supply channels and high-power performance onto one device. The presenter will also discuss new advancements in power management ICs for mobile devices.

Battery power management trends for portable designs
Texas Instruments

Battery powered portable devices require safer, faster battery charging and longer run-time within a small form factor. System safety has become a major design challenge in portable design. Attend to learn about new safety requirements and how you can improve system safety while delivering fast charge from USB/USB On-The-Go (OTG).
