Abstract
In this paper, the dynamic model of a three-level neutral point clamped (NPC) converter with neutral-point voltage-balance control (NPVBC) and input power factor correction for high-speed railway tractions is derived. And accordingly, a feedback controller is designed to meet the given voltage regulation control specifications. As the variation of converter parameters occurs, a compensation signal is yielded by an extension robust controller (ERC) to preserve the prescribed response. The compensation signal is adaptively tuned by a model error driven extension weighting controller. Some simulation results are presented to demonstrate the effectiveness of the proposed controller.
