Method And System For Controlling A Power Converter System Connected To A DC-Bus Capacitor

摘要

A method and system for controlling a power converter system with a direct current (DC)-bus capacitor connected to at least a first converter and a second converter. The first converter is with associated first current and the second converter is with associated second current. Switching states of the first and second converters are determined. The switching states of the second converter are sequenced relative to the first converter to reduce a difference of sums of the associated first and second currents between adjacent time intervals.
