| 摘要 |
The invention relates to a system for converting a first electric voltage into a second electric voltage, comprising: at least two input terminals and two output terminals; and switching members (16) disposed between the input and output terminals, which can convert the first voltage into the second voltage. At least one switching member (16) comprises at least two arms (26) connected in parallel and each arm includes an electronic switch (34) that can be controlled such as to occupy either an on-state or an off-state, said switch comprising a control electrode (36) and two conduction electrodes (38, 40) that conduct current in the on-state. The switching member (16) comprises a common control terminal (28) connected to the control electrode (36) of the switch of each arm, as well as a first common conduction terminal (30) and a second common conduction terminal (32) connected respectively to a first conduction electrode (38) and a second conduction electrode (40) of the switch (34) of each of the arms. The switching member (16) also comprises, for each arm, an inductance (42) connected between the same single electrode from the two conduction electrodes (38, 40) and the corresponding common conduction terminal (30, 32), and the inductance (42) is greater than 10 nH and substantially identical for each arm. |
