Abstract (en)
[origin: EP0973359A2] The inverter (2) has a converter network (T1/1, T1/2, C1, SW3, SW4), arranged between a DC voltage potential (U+) or reference potential (Uref), with two bridge branches, which in a stationary condition are put through alternatively on the reference potential. Also the switch network is formed by limiting the switched ON current by a limit resistance (R1) which lies in series with the storage capacitor (C2), with a further connection at reference potential. The connecting point of the storage capacitor is coupled with limit resistance with the two bridge branches of the converter network.
