Apparatus for Connecting a Shared DC Bus Link

摘要

A system for connecting a shared DC bus between multiple power converters is disclosed. The DC bus includes a positive and a negative rail across which the DC voltage is present. A pair of DC bus stabs is mounted to a PCB within the power converter. Each DC bus stab is electrically connected to either the positive or negative rail. A connector assembly is mounted to the housing of the power converter such that a first receptacle engages a plug portion of the DC bus stab. The connector assembly also includes a second receptacle extending to the exterior of the power converter. The connector assembly is positioned on each power converter such that a known distance, or one of a number of known distances, is established between adjacent connector assemblies. A DC bus assembly extends between and is plugged into the second receptacle of the two adjacent connector assemblies.
