DC transmission system and DC/DC converter used in the same
A DC transmission system transmits AC power generated by a generator to an AC distribution grid and a DC distribution grid using DC power. The DC transmission system includes an AC/DC converter, a DC/DC converter, and a DC/AC converter. The AC/DC converter outputs DC power by converting AC power from the generator. The DC/DC converter boosts a first voltage of the DC power outputted from the AC/DC converter, into a second voltage. The DC/AC converter outputs, to the AC distribution grid, AC power by converting the DC power outputted from the DC/DC converter. When the second voltage changes, the DC/DC converter controls the first voltage in response to the change in the second voltage.
