Abstract: A capacitor module includes a circuit board including a positive conductor part and a negative conductor part, and capacitors mounted on the circuit board. The capacitors have the same capacitance and the same inner current path structure. The capacitors are arranged in a direction perpendicular to main current directions of the inner current path structures of the capacitors. Each adjacent two of the capacitors are connected to the positive conductor part and the negative conductor part such that the main current directions thereof are opposite in direction to each other.

Abstract: A power converter configured to be connected to three or more voltage parts, includes three or more power-conversion circuitries to be connected to respective ones of the three or more voltage parts, and a multi-port transformer connected to the three or more power-conversion circuitries at respectively different ports. The three or more voltage parts include a vehicle drive battery and a plurality of alternating-current (AC) voltage parts. Each of the plurality of AC voltage parts is configured to provide at least one of power input to a multi-port transformer side and power output from the multi-port transformer side.
