Abstract

The current disclosure relates to the design of an apparatus for enhancing the operation and reliability of high-power multi-chip modules. The disclosed apparatus provides near-complete elimination of high frequency spectral content, while leaving the desired frequency range (1-100 kHz) of the module unaffected. In addition to the suppression of this undesirable high-frequency content, the disclosed apparatus also provides for accurate, galvanically-isolated, high-bandwidth, real-time current measurement, which is essential for some types of power electronics converters. Prior to the disclosure of this apparatus, these two features (ringing suppression and current measurement) have required physically-separate circuits for implementation, which increases the size, weight, and cost of the final implementation. The apparatus disclosed here provides both of these features in simple circuit topology that can be implemented compactly inside the geometry of a multi-chip power module.
