The three port DC-DC converter includes an arrangement of switching devices consisting of a first switching device 58, a second switching device 60, and a third switching device 62. The three port DC-DC converter also includes a pair of input channels 38,46 that provide current to the arrangement of switching devices, with the pair of input channels connected to and receiving or sending power from or to a plurality of energy sources or loads. The three port DC-DC converter further includes an output channel 54 that outputs a controlled power from or to the three port DC-DC converter. The first switching device 58, the second switching device 60, and the third switching device 62 are selectively controllable to provide a controlled power to the output channel from the plurality of energy sources or loads connected to the input channels.

摘要： A high-voltage direct-current (HVDC) transmission system includes an alternating current (AC) electrical source and a power converter channel that includes an AC-DC converter electrically coupled to the electrical source and a DC-AC inverter electrically coupled to the AC-DC converter. The AC-DC converter and the DC-AC inverter each include a plurality of legs that includes at least one switching device. The power converter channel further includes a commutating circuit communicatively coupled to one or more switching devices. The commutating circuit is configured to “switch on” one of the switching devices during a first portion of a cycle of the H-bridge switching circuits and “switch off” the switching device during a second portion of the cycle of the first and second H-bridge switching circuits.
