Full Bridge SiC Module for Charger Applications

Inhalt:
With the trend to a growing electrification of the transportation sector comes a need for more supplementary infrastructure such as chargers. For application in chargers, Danfoss Silicon Power developed a new multi-chip SiC module combining a full bridge topology in a compact frame-based package with baseplate. The module layout was designed to be conducive to a good symmetry between paralleled chips both in dynamic and static current sharing and to show robust switching behavior, avoiding parasitic effects. Approach and methods used during the design process will be detailed in this paper.
