Two different power circuit structures have been proposed for a five-level hybrid active neutral-point-clamped (5L HANPC) converters. In order to reduce the size/weight of the converter system, PCB-mounted film capacitors were selected as DC-link banks. The two arrangement of the existing power semiconductor modules are compared in this paper. The comparison includes dimension, weight, parasitic parameters,...
Conventional 2 in 1 IGBT package with 62mm×150 mm suffers from imbalance of current distribution and switching loss due to the different effect of internal electromagnetic field on multiple IGBT chips connected in parallel. A novel DBC (Direct Bonding Copper) layout was proposed in this paper to reduce the parasitics and the electromagnetic coupling between control loop and main current path. And...
To keep stray inductance low is a basic requirement in package design of IGBT modules. Meanwhile, paralleling of several switches is unavoidable in modern power electronics to insure always increasing current levels. Current balance between paralleled chips is another concern. In this paper, a simple power module, several different types of IGBT chips are respectively associated to reach the classical...
