Power modules are now commonly used in both converter and inverter circuits. The main application of the IGBT is for use as a switching component in inverter circuits which are used in both power supply and motor drive applications. This whitepaper shows the main markets IGBT modules have been designed to serve, the trends of the application, the requirements of the power device serving the application, and the type of IGBT or Intelligent Power Module (IPM) available to satisfy the trend requirements.
