Drivers and control circuitry are the interface between the signal level and the power stage within a power electronic systems. They are responsible for a safe operation of the power switches. Progress in microelectronics and in the implementation of cheap sensors allows to increase the functionality of gate drive units for MOSFETs and for IGBTs. Functions like gate current control, closer observation of voltages and of current slopes can be implemented on gate drivers at low incremental cost. Advanced solutions for the isolation barrier with enhanced bi-directional communication lead to completely new possibilities.
In the context of the development and adoption of innovative Wide-Band-Gap semiconductors, new challenges concerning robust operation at very fast switching speed and frequencies also need to be addressed in order to attain the expected gains at system level. With this tutorial we want to transfer the necessary knowledge to drive and control IGBTs and MOSFETs in a safe way.
