Yole Developpement indicates power components including discrete semiconductors, modules and IC ,market size will reach $ 20 billion in 2012. These products can meet the emerging hybrid applications, as well as a variety of applications from solar inverter to the lighting, heaters, etc., the products range from a few volts to several thousand volts are included. The analysts of Yole  believe that the market value of IGBT is about $ 1.6 billion. Super junction , the MOSFET is the direction of more high switching frequency, it is expected that in 2012 market size is $ 567 million. The new type of gallium nitride (GaN) and silicon carbide (SiC) technology whose performance can go beyond the traditional silicon components are too expensive, so they are still in the early stages of deployment. However, Yole said that these materials will impact the field of LED lighting applications, and some of the manufacturers said considering the selection of these materials. GaN and SiC are not yet ripe enough to be applicated in power electronics market. First of all, these products are asked to improve the manufacturing technology, especially in the epitaxial thickness; followed by the material is still quite expensive, making it difficult to enter the field of general consumer applications , Yole said. According to IMS Research, in 2012 the power semiconductor market is estimated to reach $ 32 billion, a growth of 5 percent from 2011.
