摘要
The DC-link ripple current of cascaded H-bridge converter has negative effects on the energy storage system, such as lower efficiency, reduced lifetime, increased grid-connecting harmonic, etc. Three kinds of passive filter, i.e. capacitor-filter, LC-filter and LC-resonant filter, and the feasibility of applying them to suppress the DC-link ripple current are analyzed. A cascaded H-bridge converter topology based on CTDC-APF (DC Active Power Filter with Coupling Transformer) is proposed, which adopts the DC active filtering circuit to absorb the ripple current of DC-link for reducing the ripple current at the DC port of cascaded H-bridge converter. Simulative results show its effectiveness. © 2016, Electric Power Automation Equipment Press. All right reserved.
