    摘要: An object of the present invention is to provide a DC/DC power conversion apparatus that can reduce the average power consumption over a wide range of DC voltage ratios. A control circuit (120) changes a switching frequency f at which IGBTs S1 to S4 perform ON/OFF operation, in accordance with a voltage ratio k (k=V2/V1) for DC voltage conversion, based on the following expressions, such that a magnitude ΔI of a current ripple flowing in a reactor Lc is a predetermined constant value irrespective of the voltage ratio k. If 1≦k 2: f=(V1/(2×L×ΔI))×(k−2)/k

    摘要: A battery unit is housed in a metallic battery case. In the battery unit, current collectors having bent portions on both sides are fixed to face surfaces of an electrode plate group of a prismatic battery. The portions of the battery case, which correspond to the bent portions, are pressed in a thickness direction. Under the pressure, a short circuit inspection for a short circuit between the battery case and the current collectors of the battery unit is executed. When a projected object exists on the bent portion, a short circuit is generated between the battery case and the current collector by pressing so that a short circuit failure caused by a shape of the current collector can be detected.

    摘要: A wave gear device is proposed having an anti-ratcheting mechanism having a simple configuration, wherein a center through-hole is formed in a cylinder hub of a wave generator, a small-diameter shaft end portion of a rotating input shaft is concentrically inserted in the center through-hole, and the two members are fastened by a fastening bolt, and a friction ring is concentrically sandwiched between the small-diameter shaft end portion and the cylinder hub and pressed in the radial direction with a prescribed force, whereby when transmission torque from the rotating input shaft to the wave generator 4 becomes excessive, slippage occurs in the rotational direction between the two members, transmission torque is limited, ratcheting generated between the two gears can be prevented.
