Summary

Power factor correction (PFC) has been implemented for some time, although 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 have gone into effect for North America, although PFC can help power supply manufacturers meet current North American energy efficiency standards. PFC can often add cost and does not benefit the end user. So its advantage to suppliers can be a way of differentiating themselves by providing an energy efficiency benefit to society. The Electric Power Research Institute says that some manufacturers have claimed energy savings up to 10% through the application of power factor correction equipment in industrial facilities. It is also a way that larger original equipment manufacturers can “meet the spec” in Europe and Asia, while selling “added value” in other regions.

The worldwide PFC market is, therefore, a potential market based on current and future regulatory actions. The forecasts in this study are based on the applications that have adopted PFC already and those likely to adopt it in the future, along with the wattage ranges identified in the IEC standard. In addition, active and passive PFC are expected to penetrate certain markets, while continuous conduction mode and discontinuous conduction mode topologies are likely to be used at certain wattage levels. Each of these factors contribute to a potential, long-term picture of the power factor correction market.

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%. This report 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?

Until recently, power factor correction has been most commonly used in motor drives and pumps. Lighting ballasts also often use PFC, in part because of the Class C requirements of EN61000-3-2. PFC implementation is likely in distributed power architectures, including embedded ac-dc power supplies. Active PFC is a requirement for Server System Infrastructure (SSI) compliance. Flat panel displays are also potential applications for PFC.

Cost is the biggest issue determining when active or passive PFC is used. Active PFC can be a more expensive solution, depending on the application. Volume production and price declines are factors that will drive the adoption of active or passive PFC. Higher-powered products are also likely to use active PFC, since it would be the most cost-effective way to bring products into compliance with the EN standard.

Driven by regulations, the development and production of PFC components is expected to continue to expand at a steady pace over the next several years. The industry is expected to remain extremely competitive, with large, multinational companies like ST Microelectronics, Fairchild, Texas Instruments and International Rectifier competing for market share with dozens of smaller regional companies worldwide. Profiles are presented of both larger players offering PFC solutions, along with some of the smaller, more specialized companies.

Companies are also looking at full digital power factor correction, although these solutions can have higher costs associated with them. PFC greatly benefits from non-linear programming. Digital implementation allows two separate functions to be integrated into a single unit and allows the power converter to be changed to accommodate different loads. This improves efficiency, which will help drive customer demand for digital control of power supplies.
