Abstract

A method and system for controlling a power converter system with first, second, and third phase legs with respective first, second, and third associated phase currents determine direction of current flow in at least two phase legs and switch states of the power converter system in response to the current flow directions to reduce ripple current in a connected direct current (DC)-bus capacitor.
