摘要 |
The power supply has inverters (A, B) connected to grounds (50, 51) and comprising electrical voltage sources (U1, U2), respectively. Arms (A1-A3) and arms (B1-B3) are extended at terminals of the sources (U1, U2), respectively. Each arm has upstream and downstream controlled switches (5, 6) e.g. MOSFET, placed in series, and a connection point is placed between the switches. The inverters have additional arms (A4, B4) connected by a bridge (7). The bridge is connected to each additional arm in a point located between upstream and downstream controlled switches (5, 6) of the additional arms. An independent claim is also included for a method for using a power supply. |
