DC support capacitor for new IGBT modules

The TDK Group has introduced a new EPCOS DC-supported capacitor. Designed for Infineon Technologies' HybridPACKTM1-DC6 IGBT modules, this component features a multi-contact configuration with six busbar terminals that are precisely matched to the IGBT module. Its excellent structural design not only provides excellent electrical conductivity, but also greatly reduces parasitic effects, such as a maximum equivalent series resistance of 0.6 m?, and an equivalent series inductance of only 25 nH. Since the ESL value of the component is extremely low, the voltage spike generated by the IGBT turn-off can be almost completely eliminated.

The new capacitor with order number B25655P4607J021 has a voltage rating of 450 V DC and a capacitance value of 600 μF. When the bottom surface of the capacitor has a heat sink temperature of 75 ° C and an ambient temperature of 105 ° C maximum, the maximum continuous operating current is 150 A. Capacitor elements are specifically designed using bulk power capacitor (PCC) technology by forming a capacitor bank with stacked windings to have a volume fill factor close to one. Capacitor housing sizes are also compact, only 140 mm x 72 mm x 50 mm.

In addition, the new capacitors are available in flat winding versions (B25655P4477J121) with the same housing. This model has a capacitance of 470 μF, a nominal voltage of 450 V DC, an equivalent series resistance of 0.8 mΩ, and an equivalent series inductance of 25 nH. At an ambient temperature of up to 105 ° C and a condensation temperature of -75 ° C, the current carrying capacity is also approximately 150 A.

In addition to the standard models, we offer capacitor models with EPCOS high voltage DC EMC filter interfaces. In summary, the combination of IGBT modules and new link circuit capacitors enables a compact inverter structure that meets xEV or industrial inverter applications.
