Abstract: The interleaved parallel voltage balancers（IPVBs） are implemented in parallel in a bipolar DC microgrid to improve the system stability and further to reduce the ripples in the current.Major challenge in the control of IPVBs comes from the design of an efficient current sharing control scheme.In this paper,an indirect inductor current sharing control method is proposed to control each single IPVB.The duty cycle is regulated with consideration of the relationships between the differences in the inductor current and the voltage of the input capacitor.Moreover,a coordinated control strategy based on an improved droop control is established to allocate the load current among multiple IPVBs.Extensive simulations show the effectiveness of the proposed methodologies.
