基于双比例积分反馈的DAB双向DC-DC变换器输出阻抗整形以实现可再生能源系统中近无纹波直流母线电压调节

This paper investigates the design and implementation of virtual-output-impedance shaping on an inverter-loaded, fuel-cell-battery-powered dc–dc converter system for achieving near-ripple-free dc bus voltage regulation. The method is based on the insertion of a second output-voltage feedback loop as can be inferred from the Mason's gain formula. Three basic modes of virtual-output-impedance shapin...
