Abstract：Under digital control，the inner current loop of the LC-type inverter is affected by the control delay，which leads to the weakening of its active damping effect. Increasing the sampling control frequency can effectivelyreduce the negative influence of digital control delay. Furthermore，in order to suppress t...
