    • A DC voltage source converter for high voltage DC power transmission comprises at least one inductor (50) and at least one chain-link converter (48) connected between first and second DC terminals (52, 54), the or each chain-link converter (48) including a chain of modules (56) in series, each module including one or more semiconductor switches (58) and one or more energy storage devices (60), the semiconductor switches (58) being controllable in use to provide a continuously variable voltage source wherein the or each chain-link converter (48) is operable when DC networks are connected in use to the first and second DC terminals (52, 54) to control switching of the modules (56) to selectively enable one DC network to charge the or each inductor (50), or enable the or each inductor (50) to discharge into the other DC network.
    • 用于高压直流电力传输的直流电压源转换器包括连接在第一和第二直流端子(52,54)之间的至少一个电感器(50)和至少一个链条转换器(48),该链接转换器 (48),包括串联的模块链(56),每个模块包括一个或多个半导体开关(58)和一个或多个能量存储装置(60),所述半导体开关(58)在使用中是可控的,以提供连续 可变电压源,其中当DC网络在使用中连接到第一和第二DC终端(52,54)时,链路转换器(48)可操作,以控制模块(56)的切换以选择性地启用一个DC网络 对所述或每个电感器(50)进行充电,或使所述或每个电感器(50)放电到所述另一个DC网络中。
