This paper discusses the characteristics and limitations of various semiconductors used in motor controls and drives. Semiconductor types discussed include the IGBT (bipolar and MOS Device), SCR, GTO and diode. Important limitations include voltage rating, current ratings, safe operating area, heat transfer characteristics and limitations due to a particular device characteristic are discussed. The focus is on the IGBT; its advantages and disadvantages are discussed, as is how it can be rated… CONTINUE READING
