Abstract: An electrical device has a housing that includes a main body and a lid both of which are electrically conductive. The lid is fastened to a top surface of a sidewall of the main body so as to cover the main body. On at least one of a bottom surface of the lid and the top surface of the sidewall of the main body, there are formed a plurality of protrusions at predetermined positions; each of the protrusions abuts against that one of the bottom surface of the lid and the top surface of the sidewall which is opposed to the protrusion. Except at those predetermined positions where the protrusions are formed, there is provided, between the bottom surface of the lid and the top surface of the sidewall of the main body, a gap via which the internal and external spaces of the housing communicate with each other.

Abstract: An electric power converter apparatus incorporates a plurality of electric power converter circuits having respective output terminals connected in common, with output power being produced from the common output terminals. Each converter circuit uses an identical switching frequency, in executing power conversion based on PWM control of switching by a plurality of switching elements. The switching operations of the respective converter circuits mutually differ in phase, by an amount determined in accordance with the currently applied PWM duty ratio. The phase difference value is predetermined for minimizing the amplitude of specific harmonic frequency components of a ripple current component in the output current from the apparatus.

Abstract: An electric power converter includes a semiconductor module, a cooler, and a pair of direct current bus bars. The direct current bus bars are connected to the semiconductor. The direct current bus bars serve as current paths between the direct current power supply and the switching element. The cooler is made of metal, and is electrically connected to ground. A proximal bypass capacitor is formed close to the switching element by a heat radiating plate integrated with the semiconductor module, the cooler, and an insulating layer interposed between them. The electric power converter further includes a pair of distal bypass capacitors, each of which has a larger capacitance than the proximal bypass capacitor has, and has a current path to the switching element of which a length is longer than a current path to the switching element from the proximal bypass capacitor.

Abstract: A noise filter is assembled to an electric power conversion device and has a metal housing casing and two capacitors connected to an external terminal of the device through which an electric power conversion circuit is connected to an external device. The two capacitors, the housing casing and the external terminal make a current loop. A magnetic flux of an alternating magnetic field generated in a part of the electric power conversion circuit penetrates in a first area and a second area formed in the current loop. A first induced noise current is induced in the current loop when the magnetic flux of the generated magnetic field penetrates in the first area. A second induced noise current is induced in the current loop when the magnetic flux penetrates in the second area so that the first induced noise current flows in a reverse direction to the second induced noise current.
