| 摘要 |
Switching devices of this type have at least two semiconductor switches, which require auxiliary power. According to the invention, additional semiconductor switches (S3/S4) with associated capacitors (C1/C2) are provided in a parallel branch to the first semiconductor switches (S1/S2). When the first semiconductor switches (S1/S2) are activated, said additional semiconductor switches (S3/S4) function in the opposite switching mode to said first semiconductor switches (S1/S2). |
