APEC 2001 Sets Records

APEC 2001, held March 4-8, 2001 at the Disneyland Hotel in Anaheim, Calif., set new records for technical session attendance, total attendance, and exhibitor participation. Each of the three sponsoring organizations, IEEE PELS, IEEE IAS, and the Power Sources Manufacturers Association (PSMA) conducted business meetings in conjunction with APEC.

The conference included component and power supply manufacturers. Attendees at this year's conference had the opportunity to attend 15 professional education seminars, 31 multispeaker technical sessions, 12 vendor application seminars, three RAP Sessions, and the Exhibit Hall.

Although the conference accepted 198 technical papers, it was still unable to accommodate more than 50% of the 435 received. Recognizing that challenge, the Steering Committee discussed another expansion of the technical program to offer six rather than five sessions in parallel. The committee will make that decision as it reviews the abstracts received for APEC 2002.

Looking ahead, APEC 2002 will be held March 10-14 at the Adams Mark Hotel in Dallas. Anyone interested in submitting a technical session proposal of practical importance in any area of power electronics should submit a 50-word abstract and a three to five page digest (via mail only) to APEC 2002, 2000L Street NW, Suite 710, Washington, DC 20036. The deadline for submission of abstracts and digests is August 3, 2001. The conference is also seeking half-day professional education seminar proposals. Papers presented at APEC must be original material, never presented or published before.

Power Supply Design Course

Power Supply Design for Performance and Reliability, will be presented at the University of Illinois at Chicago, May 1-2, 2001. This two-day course will provide an in-depth overview of “best practices” for development and manufacturing of commercial, industrial, and governmental power supply components and systems.

The course is intended for power supply design and testing engineers, power semiconductor manufacturing engineers, technical administrators, managers, students, and teachers responsible for research, development, manufacturing, and marketing of power supplies used in computers, telecom, automotive, aerospace, electric utility, transportation, and residential and industrial applications.

The course is highly focused, dealing with advanced concepts in various aspects of power supply technologies. It's based on a unique “top down” systems-oriented design approach that takes into account component- and circuit-level nonlinear interactions. It will facilitate the manufacture of robust, efficient and compact power supplies at reduced cost.

Course location will be Room 713 at the Chicago Circle Center, 750 S. Halstead St., The University of Illinois at Chicago, Chicago, IL 60607. The course is limited to a maximum of 40 attendees. The fee includes all classroom materials. For more information, call Professor Krishna Shenai at: (312) 996-2633 Fax: (312) 996-0763: or e-mail: [email protected].

Bourns, Inc. Acquires Joslyn's JESC Division

GE, RCA, Intersil, Fairchild Semiconductor History

Below is a summary, correcting and detailing February's write-up on the Fairchild acquisition of the Intersil Power Discrete Business.

1982: GE bought Intersil and formed GE Semiconductor.

1984: GE with Mitsubishi formed Powerex giving up its Thyristor products (SCRs, Triacs, Diodes).

1986: GE purchased the entire RCA Corp., and the two semiconductor groups merged forming GE/RCA Solid State. The Thyristor portion of RCA Solid State turned over to Powerex.

1988: All assets of GE/RCA Solid State were sold to the Harris Corp., who at that time was doing Hi-Rel semiconductors, but had obtained rights to make the Intel 286 microprocessor and other support chips.

Early 1990s: Harris sold the optoelectronics portion — consisting of the GE Semiconductor products — to Quality Technologies. Fairchild purchased Quality Technologies by late 2000.

1999: Harris sold all assets of the semiconductor group to a management buyout group lead by Greg Williams and backed by Sterling Holdings Corp. and Citibank. The Intersil name was selected as the name for this new independent semiconductor company.

Intersil sold the metal oxide varistor (MOV), business GE developed, to Littelfuse. Fairchild purchased Samsung's discrete power business.

2000: Intersil went IPO and is now a publicly traded company on the NASDAQ exchange. It also sold to TI, the CMOS logic business that was originally a part of RCA Solid State.

2001: Intersil decided to sell the Discrete Power business to Fairchild. This sale consists of the former RCA facility in Mountaintop, Pa.

Prior to the purchase of the discrete business of Intersil, Fairchild was spun off from National Semiconductor as a management buyout of National's discrete business.
