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: An electric power converter includes a positive and a negative electrode terminals being disposed parallel and adjacent to each other, a positive electrode side switching device connected to the positive electrode terminal, a negative electrode side switching device connected to the negative electrode terminal, an output terminal connected to a connection point between the positive and the negative electrode side switching devices, and a counter conductor facing at least a portion of the positive electrode terminal and at least a portion of the negative electrode terminal in a height direction, the height direction being a direction perpendicular to both an aligned direction and a protruding direction of the positive and the negative electrode terminals. The counter conductor is disposed along a current path of an alternating current flowing through the positive electrode terminal, the positive electrode side switching device, the negative electrode side switching device, and the negative electrode terminal.

Abstract: A power converter is provided which includes at least a first and a second magnetic device equipped with coils and an electrical circuit equipped with a conductor disposed on an imaginary plane, defined between the first and second magnetic devices. If of magnetic fluxes emitted from the coils of the first and second magnetic devices, vectors of components which are oriented in directions of axes of turns of conductors of the coils are defined as a first and a second vector, the first and second magnetic devices are disposed so that an inner product of vectors derived by projecting the first and second vectors on the imaginary plane will be positive. This minimizes electrical noise generated in the electrical circuit.
