    摘要： The invention provides a reactor to be built in a power converter. In the reactor, an induction component composed of a coil being a winding of a conductor wire, a core in which interior a magnetic path is formed and an insulation bobbin positioning and engaging a wire wound part of the coil is housed in a case to be soaked with a mold resin. Inner bottom face of the case has a plurality of surfaces having not less than two different heights letting the outside bottom of the case a reference surface, and the lower end face of the core is in contact with any of the case inner bottom surfaces excluding the lowest inner bottom surface. As a result, the reactor is suitable for on-vehicle applications to achieve reduced article variation as well as a longer service life, a shorter operation time and decreased cost.

    摘要： Three or more circuits, in which series-connected low-voltage and high-voltage side switches including MOSFETs including parasitic diodes are connected across positive and negative terminals of each of smoothing capacitors, are connected in series. One of elementary series circuits, each including a capacitor and an inductor, is disposed between any adjacent two of the circuits with the elementary series circuits set to have the same period of resonance. The MOSFETs of rectifier circuits are brought into an ON state simultaneously with the MOSFETs of a driving inverter circuit and brought into an OFF state earlier than the MOSFETs of the driving inverter circuit by a period of time not exceeding a time period equal to (period of resonance)/2. A resonance phenomenon of the capacitor and the inductor is used and conduction loss in the rectifier circuits is reduced in DC/DC power conversion performed through charging and discharging operation of the capacitor.

    摘要： Three or more circuits including a driving inverter circuit and rectifier circuits are connected in series, each of the circuits including a high-voltage side MOSFET and a low-voltage side MOSFET connected in series as well as a smoothing capacitor having positive and negative terminals between which the MOSFETs are connected. LC series circuits, each including a capacitor and an inductor, are disposed individually between one specific circuit and the other circuits with periods of resonance of the LC series circuits made equal to one another. In performing DC/DC power conversion through charging and discharging operation of the capacitors, a resonance phenomenon of the LC series circuits is used to improve conversion efficiency and achieve a reduction in size of the apparatus structure.
