Abstract

In this paper, the Pulse Train (PT) control strategy is tentatively applied to the Parallel-connected Buck Converters (PBC) with current-sharing ability. However, in Continuous Conduction Mode, undesirable low-frequency voltage oscillation will be brought about by the PT control. Therefore, the Capacitor-Current-Feedback based PT (CCF-PT) control is newly proposed to eliminate the low-frequency voltage oscillation. The experimental results indicate that, the proposed CCF-PT control method can successfully achieve effective suppression of low-frequency oscillation by properly configuring the capacitor current feedback coefficient.
