摘要
Abstract
To suppress the bus voltage ripple in modular cascaded energy storage systems under parameter mismatch conditions,an adaptive carrier phase-shift modulation strategy is proposed.Based on frequency-domain analysis and ripple vector modeling,the switching-frequency and double-frequency ripples are eliminated by constructing closed vector polygons and coordinating inter-group phases.For theoretically unsolvable regions,the ripple amplitude is minimized via extremum optimization.Simulation and experimental results demonstrate that the proposed strategy significantly reduces the bus voltage ripple amplitude and exhibits good robustness under wide-range battery state fluctuations,validating its effectiveness.关键词
