A harmonic distortion reduction system for a converter connected to a common bus is provided. Each converter of the plurality of converters may be configured to convert an alternating current (AC) through the common bus to a direct current (DC) by alternating switches of each converter of the plurality of converters to open and closed states within a switching period. The system may also include a controller circuit that may be configured to regulate the AC conducted to the plurality of converters on the common bus such that a root mean square of a ripple current component of the AC satisfies one or more specified criteria.
本发明提供了一种用于连接至公共总线的转换器的降谐波失真系统。所述多个转换器中的每个转换器可以被配置为通过使所述多个转换器中的每个转换器的开关在开关周期内交替为断开和闭合状态,将通过所述公共总线的交流电流(AC)转换为直流电流(DC)。所述系统还可包括控制器电路,所述控制器电路可以被配置为调节所述公共总线上传导到所述多个转换器的所述AC,以使得所述AC的纹波电流分量的均方根满足一个或多个指定标准。
