显示基本电路配置、控制方法和操作 机车车辆用电力变流器的模式和性能，如外部整流整流器、自整流整流器、斩波器和逆变器。描述了典型的图表和方法，但并不声称详尽无遗。 本规范的主要目的是计算功率量，如输入/输出电压、输入/输出电流、电压/电流频谱、电压/电流纹波和 电压/电流谐波。

Shows basic circuit configurations, control methods, operation modes and behaviour of electric power convertors for rolling stock such as external commutated rectifiers, self-commutated rectifiers, choppers and inverters. Describes typical charts and methods, but does not claim to be exhaustive. The main purpose of this specification is to calculate power quantities such as input/output voltage, input/output current, frequency spectrum of voltage/current, voltage/current ripple and voltage/current harmonics.
