Fundamental Data for IRF

International Rectifier Corporation is a technology pioneer and a leading designer and manufacturer of power semiconductors that refine electricity from wall outlets or batteries into a more usable form. This process, which the company calls power conversion, is conceptually similar to refining oil to produce efficient, usable fuel. Power conversion reduces costs and enhances the performance and efficiency of electrically powered products. Power conversion can be viewed in four stages: input rectification, control, switching, and output rectification.
