Vehicle with Power Electronics

A vehicle, comprising:

• a direct current circuit;
• a polyphase machine;
• a power electronics unit converting energy between the direct current circuit and the polyphase machine, the power electronics unit comprising:
• a power module;
• a driver circuit board;
• a control circuit board;
• two direct current power rails, wherein the direct current circuit is connectable to the direct current power rails;
• phase current rails, wherein the polyphase machine is connectable to the phase current rails, with a number of the phase current rails corresponding to a number of phases of the polyphase machine, wherein:
• the power module, the driver circuit board and the control circuit board are arranged in a stacked construction,
• the phase current rails are electrically coupleable to the power module, and
• the control circuit board comprises a passage for each of the phase current rails, wherein one phase current rail is feedable through each passage.
