PSMA Committees Meet During | ||||||||||||||||
| ||||||||||||||||
s reported in the last issue of the Update, the Hyatt Regency Hotel in Dallas, TX was the venue for the PSMA Annual Meeting of members during APEC 2006. In addition to the Annual Meeting, a number of PSMA committees also held meetings during that week. Most of the work of PSMA is done by the committees and APEC provides an opportunity for the committee members to meet in person, rather than by teleconference.As usual, the Marketing Committee meeting was well attended. Could it be the free lunch? Marketing Committee Chair, Lou Pechi, gave an overview of the work of the committee during the past year. He also went over the results of the PSMA survey of members.
Lou welcomed Barry Papermaster as Co-chair of the Marketing Committee and led the discussion as committee members made plans for the coming year.
Tim Cassidy, Co-chair of the Energy Efficiency Committee, discussed the activities of the committee during the past year. This is one of the most active committees and its meetings are always well attended. The committee is an industry advisor to the EPA, the California Energy Commission (CEC) as well as the New York State Energy Research and Development Authority (NYSERDA) as these organizations develop efficiency standards for electronic power supplies in different applications.
The Packaging Committee, led by Co-chairs Brian Narveson and Cian O’Mathuna, has also had a busy year. The committee made contributions to the Power Technology Roadmap Workshop. Committee members reviewed the accomplishments of the past year and developed a plan of possible activities for the coming year.
Other committees that met during the week of APEC 2006 included the Industry-Education Committee, the Magnetics Committee and the Semiconductor Committee. Members of all the PSMA committees that had meetings during this busy time were enthusiastic about their activities and look forward to another very busy and productive year. A complete listing of PSMA committees can be found on the PSMA web site. Most of the committees manage their own Technical Forum on psma.com which provides information on their current activities, upcoming industry events and resources including useful web sites. Participating in one or more committees is the best way to increase the benefits from your PSMA membership. You are encouraged to join a committee and get involved in their activities. Most committees meet about once a month for about one hour by teleconference. View a list of upcoming committee meetings. You are welcome to attend a committee meeting before making a decision to join the group. If you are interested in attending one of the meetings, please contact the Association Office for call-in information.

A Visit To A High Voltage DC Experimental | ||||||||||
| ||||||||||
 n August, 16th, representatives from the PSMA Energy Efficiency Committee visited a unique and experimental Data Center facility to see and discuss its new dc power architecture. This dc power architecture was designed and managed by Lawrence Berkeley Laboratories (LBL), EPRI Solutions and Ecos Consulting with funding for the project through the California Energy Commission (CEC). The Data Center is located at SUN Microsystems’s Newark, California facility. This on-going project has many stakeholders including Intel Corporation, Cisco Systems, Emerson Network Power and others. A complete list of the stakeholders along with more project details, are available on the web site: http://hightech.lbl.gov/dc-powering/. This experimental data center employs a high-voltage dc power architecture. The facility demonstrates that, by using high voltage dc bus (380 Vdc), the entire power system can be simplified, efficiently deployed and result in lower utility bills. After the front-end ac to dc conversion, the 380 Vdc is distributed at the frame level to racks of servers that have been modified to accept the high voltage dc. The high voltage dc is converted to a standard intermediate bus architecture within the servers. This data center is defined as "DC Power" to distinguish it from the traditional "AC Power" because of the nature of the power distribution. In a traditional data center, significant losses occur due to ac to dc conversion from the utility supply and then the ac to dc double conversion in an online UPS deployed at the front-end for the system backup required to meet availability objectives. In the dc approach, a dc UPS (battery plant) eliminates the need for double conversion. In a traditional "AC Power" data center the each stage of conversion incurs some losses – the efficiency of the traditional UPS is typically 88-92%; the efficiency of the power distribution (PDU) is typically 98-99%; the efficiency of the power supply (PSU) is 68-72% and the efficiency of the dc-dc converters is typically 78-85%. As a result, the cumulative power system efficiency is between 45 to 56%. In addition, the facility requires additional cooling due to heat generated by the losses at every power conversion stage and a larger sized motor generator for long term reserve power. In this "DC Power" data center, the entire system is dc operated eliminating several conversions and resultant losses. Since this is an experimental facility to show the benefits of dc distribution, the facility also provided a comparison between the traditional ac distribution and the experimental dc distribution system. The "DC Power" power architecture replaces the front-end ac UPS by a dc UPS (ac-dc front end rectifier with a battery backup unit (BBU)) that delivers 380Vdc output. This 380 Vdc is then converted to an intermediate bus 12 Vdc distribution followed by board level VRMs to provide the power for the load. The dc distribution system eliminates the need for double conversion associated with the traditional ac UPS and Power Distribution Unit (PDU) and the ac-dc power supply resulting in an overall efficiency improvement between 10 to 20% for the facility. With today’s kwh utility costs, a 15% efficiency improvement results in a $2.7 million yearly savings in utility bills for a 10Mw system. With significant growth in the size and number of data centers and servers expected in coming years, this saving is expected to increase to $13 million for future 50 mw data centers. This "DC Power" design took a different approach at the power systems architecture from the efficiency and cost-related issues. The power system components were not custom designed and were any special customization required. This data center looked like a typical telecom central office power plant except the distributed voltage was 380 Vdc instead of 48 Vdc. High voltage dc bus architectures have been previously used only in some special high-end computer applications. But now, with higher energy prices and the emphasis on high efficiency, the power supply industry needs to take a fresh look at this dc power architecture and be an active participant in its development for the benefit of companies, society and the bottom line. There are still a number of technical and cost issues that need further study and discussion. These include practical issues such as safety, reliability, and grounding and equipment issues relating to connectors, arcing, and short-term and long-term costs. The "DC Power" project team welcomes any input on these issues. A comprehensive report on all these aspects of DC Powering will be completed during the fall of 2006.
