DC-DC converter, power converter, power generation system, and DC-DC conversion method

摘要

The DC-DC converter (1) according to the embodiment is disposed between the first and second switching circuits (10, 11) and between the first switching circuit (10) and the second switching circuit (11). Inductance elements (13, 13a, 13b) and a transformer (12), and a control unit (20) for operating the first and second switching circuits (10, 11). The control unit (20) sets a predetermined operation ratio for the first and second switching circuits (10, 11), and based on the set operation ratio, the first and second switching circuits (10, 11) Adjust the length of the operation period. According to the DC-DC converter (1) concerning embodiment, the fall of power conversion efficiency can be suppressed easily.
