Zusammenfassung: | In this uninterruptible power supply system, a first converter (2) for generating a DC voltage and a second converter (5) for regenerating power are separately provided. DC buses (L1 to L3) are connected to the second converter (5) and to a bidirectional chopper (6) with bus bars (B1 to B3). The bus bars (B1 to B3) are formed into a laminated bus bar (24). First semiconductor modules (M1d, M2d) included in the second converter (5) and second semiconductor modules (M1a to M1c, M2a to M2c) included in the bidirectional chopper (6) are each mounted on the laminated bus bar (24) and connected to the bus bars (B1 to B3). The bus bars (B1 to B3) and the first and second semiconductor modules (M1a to M1d, M2a to M2d) are configured as an integrated converter unit (7). |
