摘要： A load commutated inverter (LCI) drive system for a synchronous electrical machine is provided. The system may include a first supply bridge and a second supply bridge, each of which may include an alternating current to direct current (AC-to-DC) source side converter, a DC link circuit, and a DC-to-AC load side inverter. The system may include a controller for selectively controlling at least one of the first supply bridge and the second supply bridge by selective firings of SCRs. The electrical power outputted from the first supply bridge and the second supply bridge may be combined by an output delta-wye electric power transformer and supplied to the electrical machine. The LCI drive system may further include one or more input electric power transformers configured to supply an input electric power to the first supply bridge and the second supply bridge.

摘要： Systems and methods for converting power are presented. The power conversion includes conducting load current through a first current path of multiple current paths in a power conversion unit using switches, diodes, or a combination thereof. The power conversion also includes blocking one or more additional current paths of the multiple current paths in the power conversion unit using one or more of the switches, one or more of the diodes, or a combination thereof. Furthermore, the power conversion includes reducing potential voltage stress on the one or more switches by using one or more voltage stress reduction switches to reduce a voltage that is blocked by the one or more blocking switches or diodes by connecting an end of each of the one or more switches opposite to a blocking edge to an intermediate voltage node.
