Abstract:
1. A stacked structure of a power converter, comprising: a power conversion circuit that provides an output or an input of alternating current and is composed of a plurality of parallel-connected power semiconductor element modules and at least one heat sink configured to cool the power semiconductor element modules; wherein the plurality of parallel-connected power semiconductor element modules are arranged in two rows on the at least one heat sink relative to a ventilation direction of air for cooling the at least one heat sink; and an odd number of the plurality of parallel-connected power semiconductor element modules are arranged in a first phase, an odd number of the plurality of parallel-connected power semiconductor element modules are arranged in a third phase, and an even number of the parallel-connected power semiconductor element modules are arranged in a second phase; the at least one heat sink includes a first heat sink and a second heat sink; and at least one of the power semiconductor element modules in the first phase and at least one of the power semiconductor element modules in the second phase are arranged in the first heat sink, and at least one of the power semiconductor element modules in the third phase and at least one of the power semiconductor element modules in the second phase are arranged in the second heat sink.
