Abstract
In DC microgrids, constant power loads (CPLs) would lead to a destabilizing effect that may cause the main bus voltage oscillation. Hence, most researcher are exploring the stabilization methods for DC/DC buck converters feeding CPLs. In practical applications, buck converters are always cascaded with LC input filters to prevent the switching harmonics from returning into the source. With the addition of input filters, the system stability would be more severe and the complexity is increasing. In this paper, for buck converters with LC input filters, a linear feedback control is proposed to overcome the negative impedance characteristic and stabilize the system. Moreover, the accurate load demand sharing among DGs and high quality of load voltage are guaranteed. Simulation and experimental results verify the effectiveness of the proposed methods.
