摘要： An electric power source device has a transformer, a primary-side semiconductor module, a secondary-side semiconductor module, a secondary-side electrical component, a base plate and a circuit substrate on which substrate-side electrical components are mounted. The primary-side semiconductor module has a larger exterior size than the secondary-side electrical component. The primary-side semiconductor module and the secondary-side electrical component form a stacked section. In the stacked section, the secondary-side electrical component is stacked, in a vertical direction, i.e. a direction of a normal line of a mounting surface of the base plate, on the primary-side semiconductor module. The primary-side semiconductor module is directly mounted on the mounting surface. At least a part of the substrate-side electrical components is arranged inside of the primary-side semiconductor module in a horizontal direction, and inside of a second surface of the stacked section toward the mounting surface along the normal line.

摘要： A power supply unit includes: a transformer; a primary component that constitutes a primary circuit connected to the transformer; a secondary component that constitutes a secondary circuit connected to the transformer; a choke coil; a base plate including the transformer, the primary component, the secondary component and the choke coil; a metal plate connected to the base plate; and a connecting member connecting the primary component and the transformer. The primary component and the transformer are laminated to constitute a first laminating body. A part of the metal plate is disposed closer to the transformer than the primary component, and the metal plate and the transformer are electrically connected by a ground line. A connection point between the ground line and the metal plate is located closer to the transformer than the primary component.

摘要： An electric power conversion device has a transformer, a DC-AC conversion circuit, an AC-DC conversion circuit and a control circuit. The control circuit calculates an input current instruction value (Iref) based on a difference value (ΔV) between an output voltage (Vout) of the AC-DC conversion circuit and an output voltage instruction value (Vref). A comparator compares an input current (Iin) of the DC-AC conversion circuit with the value (Iref). The DC-AC conversion circuit is controlled by the comparison result of the comparator. The control circuit correctly determines an occurrence of an abnormality state of the electric power conversion device based on the operation state of the comparator, the difference value (ΔV) between the output voltage (Vout) of the AC-DC conversion circuit and the output voltage instruction value (Vref), and the input voltage (Vin) of the DC-AC conversion circuit without using any output current of the AC-DC conversion circuit.

摘要： A power supply apparatus includes a transformer which has a primary coil and a secondary coil, a primary side semiconductor component which configures a primary side circuit connected to a side of the primary coil of the transformer, a secondary side semiconductor component which configures a secondary side circuit connected to a side of the secondary coil of the transformer, a choke coil which is connected to the secondary side semiconductor component, and a base plate on which the transformer, the primary side semiconductor component, the secondary side semiconductor component, and the choke coil are mounted. Any two of the transformer, the primary side semiconductor component, the secondary side semiconductor component, and the choke coil configure a first stacked body stacked in a normal direction of the base plate, and other two of the transformer, the primary side semiconductor component, the secondary side semiconductor component, and the choke coil configure a second stacked body stacked in the normal direction of the base plate. The power supply apparatus has a pair of first lines connecting the primary side semiconductor component and the transformer to each other, and a pair of second lines connecting the transformer and the secondary side semiconductor component to each other. The first lines and the second lines respectively have a pair of first current paths and a pair of second current paths which are arranged so as to be adjacent to each other and are configured so that currents flow in the normal direction of the base plate. At least one of the pair of the second current paths is adjacent to at least one of the pair of the first current paths in a second direction orthogonal to a first direction in which the pair of the first current paths are adjacent to each other. The first current paths and the second current paths adjacent to each other in the second direction are configured so that currents flow therethrough in directions opposite to each other.
