EL SEGUNDO, Calif. — September 2005 — International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, will outline recent advancements in power management technology driving gains in energy savings and performance at an industry seminar in Seoul October 26.

Organized by EDN Asia, the day-long event will bring together technology companies and design engineers and managers to focus on one of the most important topics of the semiconductor industry – power management.

"As leaders in the field, engineers look to International Rectifier to guide them in simplifying the increasing design complexities they confront in managing power efficiently,” said Stephen Tsang, senior vice president of Sales at International Rectifier. "This seminar provides us with a great opportunity to support continued design innovation underway inside Korea by presenting the most recent advancements in power management,” he continued.

IR will present two advanced topics at the seminar:

Toshio Takahashi, director of IR’s Digital IC Design Center, will discuss iMOTION™, the widely-acclaimed integrated design platform for appliance Motor Control pioneered by IR. "IR's mission is to drive the adoption of energy-saving Motor Control technology. Over the course of the seminar, engineers will gain valuable insight into our innovative power management approaches for a full range of Motor Control applications,” said Takahashi.

The iMOTION design platform integrates digital, analog and power technologies together with sensor-less control algorithms in a flexible, mixed signal chip set to simplify Motor Control designs and bring energy-efficient, cost-effective appliances to market faster. By adding a few external components and a microcontroller, designers have a complete variable-speed motor drive at their fingertips.

Ken Boyden, International Rectifier’s director of Computing and Communications Field Applications Engineers, will present advanced design techniques for AC-DC power factor correction (PFC) for digital TV applications using IR's new IR1150 µPFC™ family of control ICs. “Our µPFC control IC simplifies and shrinks the PFC control circuit, making it a smart solution for a range of computing, home appliance and home entertainment products. In these applications, digital TVs being one example, manufacturers are implementing PFC in response to emerging energy efficiency standards worldwide,” said Boyden.

With unity PF as the ultimate goal, the IR1150 enables 0.999 PF with only 4% total harmonic distortion, enabling AC-DC applications to conform to international legislative requirements such as IEC 1000-3-2 in Europe, JIC C 61000-3-2 in Japan and the China Compulsory Certificate (CCC) for products using more than 75W. The IR1150 control IC simplifies effective PFC solutions, and enables a single design that can be used worldwide.
