This paper deals with the switching behavior of a SiC MOSFET in a TO-247 package. Based on simulations, critical parasitic inductances in the circuit layout are analyzed and their effect on the switching losses highlighted. Especially the common source inductance, a critical parameter in a TO-247 package, has a major influence on the switching energy. Crucial design guidelines for an improved double...
The power losses of three-level neutral-point-clamped (NPC) converters and their AC-filters with iron and amorphous core inductors designed for a bipolar low voltage direct current (LVDC) distribution network are evaluated. The main objectives of the LVDC distribution network are improved energy efficiency, power quality and reliability and higher power transmission capacity and integration of ICT...
This paper describes the design and development of a 6 kA/1.1 kV non-destructive testing system, which aims for short circuit testing of high-power IGBT modules. An ultra-low stray inductance of 37 nH is achieved in the implementation of the tester. An 100 MHz FPGA supervising unit enables 10 ns level control accuracy of the short-circuit duration, protection triggering, and acquisition of the electrical...
