Compact stacked power modules for minimizing commutating inductance and methods for making the same

摘要

A compact stacked power module including a positive direct-current-bus-voltage plate having a positive-plate surface and a negative direct-current-bus-voltage plate having a negative-plate surface. The compact stacked power module also includes an alternating-current output plate having opposing first and second output-plate surfaces, a first semiconductor switch contacting the negative-plate surface and the first output-plate surface, and a second semiconductor switch contacting the positive-plate surface and the second output-plate surface. The compact stacked power module further includes a capacitor contacting the negative-plate surface and the positive-plate surface, wherein the capacitor is electrically in parallel with the first and second semiconductor switches.
