Through　theoretical　analysis,　a　selection　way　of　feedback　currents　for　LCL-filter-Based　double　closed-loop　control　system　with　passive　damping　of　Shunt　APF　was　proposed.　The　range　of　damp　resistor　and　proportional　gain　values　which　make　the　system　stable　were　extended　obviously,　when　getting　the　feedback　current　of　inner　loop　from　the　inverter　side　and　getting　feedback　current　of　outer　loop　from　the　grid　side,　compared　to　the　traditional　way　of　getting　feedback　current　of　both　internal　and　external　loop　from　the　grid　side.　It　means　that　the　system　is　more　stable　with　a　slight　reduction　of　steady-state　accuracy　at　high　frequency　harmonics.　Since　the　high　frequency　harmonics　content　is　less,　the　reduction　is　almost　negligible.　So,　only　a　smaller　damping　resistor　is　required　to　make　the　system　stable　and　achieve　good　steady-state　accuracy.　It　reduces　the　loss　of　damping　and　the　risk　of　device　heating.　Since　the　range　of　proportion　gain　values　which　make　the　system　stable　is　larger,　the　proportion　gain　value　is　increased　properly　to　improve　steady-state　accuracy　and　dynamic　response　speed　of　the　system.　The　simulation　result　verifies　the　correctness　and　effectiveness　of　the　proposed　selection　method　of　feedback　currents.　©　2016,　Harbin　University　of　Science　and　Technology　Publication.　All　right　reserved.
