Darnell Identifies PFC Opportunity for 1.3 Billion Units

February 26, 2006 by Jeff Shepard

Darnell Group Inc. has announced publication of its latest report, "Power Factor Correction: Potential Market Forecasts, Application Trends & Competitive Environment." This new, First Edition 106-page report provides a detailed and in-depth examination of the trends driving the adoption and utilization of power factor correction (PFC) in a wide variety of application systems.

The report provides detailed, quantitative, worldwide and regional unit forecasts for North America, Europe and Asia. These are broken down by applications that are likely to adopt PFC; the wattage categories expected to utilize active versus passive PFC; and the wattage splits for discontinous versus continuous conduction mode.

The total worldwide market for PFC (both passive and active) is expected to be approximately 1.3 billion units in 2006, increasing to 2.2 billion units in 2011, a compound annual growth rate of 11.4%. Darnell's Power Factor Correction study looks at three questions: (1) How quickly will PFC get adopted? (2) What applications are the most likely candidates for adoption? (3) What will be the mix of active versus passive PFC?

The report also analyzes the competitive environment in this market, including profiles of over 20 leading suppliers of semiconductor components used in PFC circuits. Additionally, the report provides market shares for the top power factor correction semiconductor manufacturers.

Power factor correction (PFC) has been implemented for some time and is highly driven by regulations. It got a boost in power supplies in 2001, when the International Electrotechnical Commission (IEC) standard 61000-3-2 went into effect in Europe. This specification required new electronic equipment consuming more than 75W to meet certain standards for harmonic content, which basically required the use of PFC. Britain, Japan and China soon adopted similar standards, and any company selling equipment into these regions needed to meet these requirements. No similar requirements hae gone into effect for North America, although PFC can help power supply manufacturers meet current North American energy efficiency standards.
