摘要

电压源变换器开关间的死区导致输出电压的降低一直是研究人员面临的难题。死区消除解决了这一问题,但需要电压源变换器输出电流精确过零。本文研究了并联型有源电力滤波器(SAPF)运行中的死区消除问题。在这里,随着电能质量的提高,VSC被用于光伏源集成。电网同步采用改进的二阶序列滤波器-锁频环(Modified SOSF-FLL)。在MATLAB中对该策略进行了仿真和验证。

Multi-functional Power Converter Operation for SAPF application and PV Integration with Dead-band Elimination Technique
Reduction in the output voltage due to dead band in between switches of voltage source converter is always challenging for the researcher. Dead band elimination solves the purpose, but it requires exact zero crossing of voltage source converter (VSC) output current. This paper deal with the dead band elimination in shunt active power filter (SAPF) operation. Here, along with power quality improvement, VSC is used for photovoltaic source integration. For the grid synchronisation Modified second-order sequence filter- frequency locked loop (Modified SOSF-FLL) is used. The proposed strategy is simulated and verified in MATLAB.
