具有自平衡和升压能力的有源中点箝位七电平逆变器
Active-neutral-point-clamped Seven-level Inverter with Self-balancing and Boost Capabilities
摘要
Abstract
A novel active-neutral-point-clamped(ANPC)seven-level inverter based on the principle of switched-capacitor is proposed in this paper,which employs ten switches,two diodes and one switched-capacitor.With an input amplitude of V'DC the peak output from this topology can reach 1.5VDCthrough the switched-capacitor.Compared with other APNC inverters,the novel topology has lower switch stress and a higher Boost capability.Without the auxiliary control methods,the voltage-sharing capacitors in the DC link can be self-balanced at 0.5V'DC and the switched-capacitor can be self-balanced at VDC The operation principle for the proposed topology and the self-balancing mechanism for capacitors are described in detail.Through a comparison with the latest topologies,the advantages of the proposed topology such as fewer components,a higher Boost capability,lower overall voltage stress and a self-balancing capability of capacitors are also demonstrated,showing that it is suitable for distributed generation,electric vehicles and other applications.Finally,the Boost capability of this topology and the self-balancing capability of capacitors were verified by simulation and experimental results.关键词
