Abstract

In pursuit of developing a low-inductance power module, we engineered a module featuring a POL double-layer facing structure. This design demonstrated a mutual inductance cancellation effect of 14.9 nH, reducing the module's parasitic inductance to 8.7 nH. Furthermore, by decreasing the inter-module distance to 1.0 mm in the simulation, the mutual inductance cancellation effect was enhanced, resulting in a reduction of the module's parasitic inductance to 5.5 nH.

This manuscript is based on the presentation delivered at the 2025 ICEP-IAAC.[1]
