    摘要: A voltage conversion apparatus is disclosed in which a current passes through first and second loop circuits alternately in accordance with ON/OFF operation of a first switching element provided in the first circuit. The direction of a magnetic field through the first loop circuit formed at the ON operation is the same as a direction of a magnetic field through the second loop circuit formed at the OFF operation. The first loop circuit and the second loop circuit are provided on opposite sides of a printed circuit board, respectively, in such a manner that the first loop circuit and the second loop circuit are opposed to each other. A heat sink is provided on a surface of the printed circuit board. A solid pattern of a metal material is provided on an inner layer of the printed circuit board to be connected to the heat sink via a through hole.

    摘要: An object of the present invention is to effectively reduce noise generated when driving a three-phase brushless motor. A noise reduction arrangement applied to a three-phase brushless motor is disclosed, wherein respective current loops, which are generated when two switching elements Q1 and Q2 related to U-phase are turned on or off in reversed phase with respect to each other, are opposed to each other in a direction of the normal to a board; respective current loops, which are generated when two switching elements Q3 and Q4 related to V-phase are turned on or off in reversed phase with respect to each other, are opposed to each other in a direction of the normal to the board; and respective current loops, which are generated when two switching elements Q5 and Q6 related to W-phase are turned on or off in reversed phase with respect to each other, are opposed to each other in a direction of the normal to the board.
