Vehicle with Power Electronics

摘要

A vehicle includes a power electronics unit for converting energy between a DC circuit and a polyphase machine, wherein the power electronics unit has a power module, a driver board, and a control board. The power electronics unit has two DC current rails, wherein the DC circuit can be connected to the same, and the power electronics unit has phase current rails, wherein the polyphase machine can be connected to the same. The number of the phase current rails corresponds to the number of the phases of the polyphase machine. The arrangement of the power module, the driver board, and the control board corresponds to a stacked or sandwiched construction, the phase current rails are electrically connected to the power module, and the control board has a passage for each of the phase current rails, wherein one phase current rail is fed through each passage.
