| 摘要 |
The invention relates to an energy storage device (1) for generating an n-phase supply voltage, where n = 1, with n energy supply branches which are connected in parallel and which are each connected to one of n phase connections, wherein each of the energy supply branches has a large number of energy storage modules (3) which are connected in series and which each comprise: an energy storage cell module (5) which has at least one energy storage cell (5a, 5n), and a coupling device (9) with coupling elements (7, 8) which are designed to switch or to bridge the energy storage cell module (5) selectively into the respective energy supply branch, wherein those coupling elements (8) of the coupling devices (9) which are designed to bridge the energy storage cell module (5) in the respective energy supply branch comprise normally-on semiconductor switches (8a). The other coupling elements (7) can comprise normally-off semiconductor switches (7a) in this case. |
