Title: UNINTERRUPTIBLE POWER SUPPLY DEVICE
Abstract:
In this uninterruptible power supply device, a first converter (2) for generating direct-current voltage and a second converter (5) for regenerating electric power are separately provided, and bus bars (B1-B3) are used to connect direct-current bus lines (L1-L3) to the second converter (5) and also to a bidirectional chopper (6). The bus bars (B1-B3) are constituted of a laminate bus bar (24), and first semiconductor modules (M1d, M2d) included in the second converter (5) and second semiconductor modules (M1a-M1c, M2a-M2c) included in the bidirectional chopper (6) are mounted on the laminate bus bar (24) and are connected to the bus bars (B1-B3). The bus bars (B1-B3) and the first and second semiconductor modules (M1a-M1d, M2a-M2d) are configured as a single converter unit (7).
