How to select input capacitors for a buck converter
by Maniing Xie, System Application Engineer, Power Design Systems, Texas Instruments Electromagnetic interference (EMI) can create serious issues for manufacturers in an industrial environment. A buck converter generates a pulsating ripple current with high di/dt at the input. Without input capacitors, ripple current is supplied by the upper power source. Printed circuit board (PCB) resistance […]
DC link capacitor for IGBT modules
TDK Corporation presents a new EPCOS DC link capacitor that has been specifically designed for the HybridPACK™ 1-DC6 IGBT module from Infineon Technologies. The outstanding features of this component are the six busbar terminals with dimensions that are matched precisely to fit the IGBT module. This multiple contacting produces an excellent current capability while at […]
