Classification: CPC H | IPC H

Claim 15:
16. The bridge circuit as claimed in claim 15, wherein the power semiconductor switches are arranged such that the first power semiconductor switch in the switched-on state allows a current flow from the first DC voltage connection to the first intermediate point, the second power semiconductor switch in the switched-on state allows a current flow from the first intermediate point to the AC connection, the third power semiconductor switch in the switched-on state allows a current flow from the AC connection to the second intermediate point, the fourth power semiconductor switch in the switched-on state allows a current flow from the second intermediate point to the second DC voltage connection, the fifth power semiconductor switch in the switched-on state allows a current flow from the first intermediate point to the neutral connection and the sixth power semiconductor switch in the switched-on state allows a current flow from the neutral connection to the second intermediate point, and further comprising an anti-parallel diode respectively arranged for each power semiconductor switch to allow a current flow opposite to the current flow direction that is enabled in the switched-on state of the respective power semiconductor switch.
