IGBT Press-packs for the industrial market
We present a newly developed 4500 V and 2000 A Press-Pack IGBT module for power transmission and industrial voltage drives applications. The module employs SPT IGBT chips with exceptionally low losses and high Safe Operating Area (SOA). The use of SPT IGBT chips in this Press Pack IGBT module allows for higher power densities and the package provides a highly flexible modular platform with very...
متن کاملInnovative Metal System for IGBT Press Pack Modules
Two important design aspects encountered in IGBT press pack modules used for HVDC applications are short circuit failure mode (SCFM) and intermittent operating life (IOL) capabilities. The requirement that press-pack IGBT (PPI) fail safely into a short causes a design conflict with the module’s desired capability to survive a high number of power cycles in normal operation. An innovative materi...
متن کاملHigh Frequency Behavior of High Power IGBT Modules
Sharp voltage gradients act as a stimulus for high power IGBT modules, which can exhibit a potentially instable high frequency behaviour. In effect, they can act as a radio frequency (RF) amplifier and under certain operating conditions the interaction between the device and the control or the external circuit can cause self-sustaining oscillations or the enhancement of the unevenness in curren...
متن کاملPressure contact IGBT , the ideal switch for high power applications
Abstract Models and experimental data are used to predict the performance of large area pressure contact IGBTs, offering ratings equivalent to the largest power conventional technology devices. Differences in the electromechanical characteristics of pressure contact devices, when compared to substrate mounted devices, are reviewed and how these influence the potential performance of devices wit...
متن کاملHigh Power Soft – switching IGBT DC – DC Converter
A soft-switching topology for high power buck converter is proposed. Zero-current turn-on and zero-voltage turn-off is achieved without auxiliary switches. All active switches in the converter transmit power to the load equally. Converter control is simple despite four active switches. Converter operation is described and DC analysis is carried out. All operation modes are identified. The condi...
