Epcos has developed a new PCC (power capacitor chip) with a bus-bar that fits the IGBT modules of all well-known suppliers. Its compact cube-like design features dimensions of 280 mm x 110 mm x 120 mm and a volume fill factor of nearly 1, enabling the design of space-saving converters. Moreover, time-consuming and expensive assembly work and symmetry resistors are no longer necessary, as is the case with other capacitor types. At a rated voltage of 900 V d.c. the PCC offers a capacitance of 1000 mF. The ESL for the entire PCC, including the bus-bar, is a maximum of 15 nH. Therefore, IGBT modules with steep switching edges do not experience any notable voltage overshoots.
