LONDON The market for power semiconductors in industrial motor drives is set to grow from $1 billion in 2007 to $1.3 billion in 2010, with the growth mainly driven by an increasing fraction of motors electronic drives, according to IMS Research (Wellingborough, England). Those figures imply a annual growth rate of about 9.1 percent.
Power semiconductor components are the biggest revenue opportunity used in industrial motor drives and the market size is about twice the size of the combined market for microcontroller and analog-based components. "IGBT modules are used in the large majority of industrial motor drives, explained Jamie Fox, an IMS Research analyst, in a statement. "As well as standard IGBT modules, intelligent power modules and power integrated modules are also used."
Power Integrated Modules have the highest growth forecast, of 10.8 percent annually.
Most of the market is for modules; however there is also a small market for discrete transistors and power ICs. Significant changes in the basic bill of materials are not expected in the next few years. Performance trends for power semiconductors include a demand for reduced heat losses, better temperature tolerance and higher power densities.
