DC-DC boost and buck converter comprising a boost converter and components enabling the boost converter to act as a buck converter

摘要

The present invention concerns a DC-DC boost and buck converter comprising a boost converter (16a) and components (S1,D2) enabling the boost converter (16a) to act as a buck converter, a first input (1) of the boost converter (16a) being connected to a first input (10a) of the DC-DC boost and buck converter, a second input (2) of the boost converter (16a) being connected to a second input (11a) of the DC-DC boost and buck converter, a first output (3) of the boost converter (16a) being connected to a first output (12a) of the DC-DC boost and buck converter, characterized in that the components (S1,D2) enabling the boost converter (16a) to act as a buck converter are a first (S1) and a second (D2) switches, a first terminal of the first switch (S1) is connected to the second output (4) of the boost converter (16a), a second terminal of the first switch (S1) is connected to a first terminal of the second switch (D2) and to the second output (13a) of the boost and buck converter and the second terminal of the second switch (D2) is connected to the first input (1) of the boost converter (16a).
