IPM (Intelligent Power Module), i.e. intelligent power modules. These are relatively small devices that have very high performance. They are characterized by high speed and low power losses. The modules are made of IGBT or MOSFET transistors, improvement diodes, gate controllers and auxiliary elements. Sometimes IPM modules have built-in measuring resistors that provide control of the current flowing through individual branches of the bridge. Placing almost all the necessary elements in one housing reduces the size of the controller by almost half.
