摘要： A magnetically coupled reactor includes a coupled core member, a first coil, and a second coil. The coupled core member includes a first core and a second core made of a magnetic material and disposed to face each other, a coil channel, and a sheet-like magnetic body by which a coupling portion between cores is put between the first core and the second core at an outer portion of the first and second cores. Each coil is wound around a leg through the coil channel in a lap winding manner such that the coils are overlapped on top of each other in the coil channel when seen in an axial direction. The sheet-like magnetic body extends from the coupling portion between coils into the coil channel and includes a portion arranged between coils located between the coils in the axial direction.

摘要： An electric power conversion circuit comprises U-phase and V-phase switching circuits, a transformer, and an α-phase switching circuit. A primary winding of a transformer is connected between the U-phase switching circuit and the V-phase switching circuit, and both ends of a secondary winding are connected to the α-phase switching circuit. The α-phase switching circuit comprises positive and negative terminals, a half bridge including and two switching devices, and a voltage divider circuit. The half bridge is provided between the positive terminal and the negative terminal, and a common connection point between the two switching devices is connected to one end of the secondary winding. A voltage divider output point of the voltage divider circuit is connected to the other end of the secondary winding.

摘要： The present invention provides a power conversion circuit system in which a circulating current can be reduced by accurately detecting the circulating current, to thereby improve efficiency in power conversion. The power conversion circuit system includes a power conversion circuit composed of a primary conversion circuit having left and right arms and a secondary conversion circuit having left and right arms, and a control circuit for controlling switching of switching transistors in the primary and secondary conversion circuits. The control circuit detects the circulating current at at least one of timings lagged by π/2+φ/2 from at least either a peak timing or a valley timing in a carrier counter where φ represents a difference in phase between the primary and secondary conversion circuits, and performs feedback control for reducing the detected circulating current to zero.
