Semiconductor protection tips for 3-level topologies

Supplied by Semikron Pty Ltd on Monday, 21 October, 2019

3-level topologies are mainly used in UPS and solar applications due to their high efficiency and low harmonic distortion of the grid. Essential for the design of the driver is to limit the voltage at the IGBT and handling of short circuits.

This application note describes the control and protection of power semiconductors in 3-level NPC and TNPC topologies.
