Title:
DC-DC CONVERTER AND VEHICLE
Document Type and Number:
Japanese Patent JP2022124673
Kind Code:
A
Abstract:
To inhibit heat generation in an element by reducing loss in the element.SOLUTION: A DC-DC converter according to the present disclosure includes a DC-AC conversion circuit, a transformer, a plurality of rectifier circuits, a plurality of smoothing circuits, and an output circuit. The DC-AC conversion circuit converts a DC input voltage to a primary side AC voltage. The transformer includes a primary side coil to which the primary side AC voltage is applied, and a plurality of secondary side coils that are magnetically coupled with the primary side coil. The plurality of rectifier circuits are provided in the plurality of secondary side coils in one-to-one correspondence, and each of the plurality of rectifier circuits outputs a rectified voltage obtained by full-wave rectification of a secondary side AC voltage outputted from the corresponding one of the plurality of secondary side coil. The plurality of smoothing circuits are provided in the plurality of rectifier circuits in one-to-one correspondence, and each of the plurality of smoothing circuits smooths a rectified voltage outputted from the corresponding one of the plurality of rectifier circuits. The output circuit is connected to each of output terminals of the plurality of smoothing circuits, and outputs a DC output voltage.SELECTED DRAWING: Figure 1
