Title:
DIRECT CURRENT POWER TRANSMISSION SYSTEM AND DC-DC CONVERTER USED IN SAME
Document Type and Number:
WIPO Patent Application WO/2018/135031
Kind Code:
A1
Abstract:
A direct current power transmission system (100#) transmits, using direct current power, alternating current power to an alternating current power distribution system (30) and a direct current power distribution system (20), said alternating current power having been generated by a power generator (12). The direct current power transmission system is provided with an AC-DC converter (110), a DC-DC converter (120), and a DC-AC converter (140). The AC-DC converter converts, into direct current power, the alternating current power transmitted from the power generator. The DC-DC converter boosts, to a second voltage, a first voltage of the direct current power converted by the AC-DC converter. The DC-AC converter converts, into alternating current power, the direct current power converted by the DC-DC converter, and outputs the power to the alternating current power distribution system. In the cases where the second voltage fluctuated, the DC-DC converter controls the first voltage in response to the fluctuation of the second voltage.
