高压直流断路器的换相原理，其中在电路中的电流被带到从预充电电容器的抵消电流为零。电路功能进行了描述，使这一过程更容易的断续器和典型的组件要求进行了讨论。电流中断和能量吸收的功能应分开，为此，一种类型的浪涌抑制器进行了说明。使用这种类型的断路器，多端HVDC系统可以像类似的AC系统一样运行，对终端控制的依赖性最小。作为一个例子，抽头线。
The commutation principle for HVDC circuit breakers is described whereby the current in the circuit is brought to zero by a bucking current from a precharged capacitor. Circuit features are described to render this procedure easier for the interrupter and typical component requirements are discussed. The functions of current interruption and energy absorption should be separated; to this end, one type of surge suppressor is described. With breakers of this type, multi-terminal HVDC systems could be operated much like comparable AC systems, with only minimal dependence on terminal controls. A tapped line is given as an example.
