system for a step increase of 100% of the load current at t = 116.7 ms. In other terms, the value of the load
resistance is changed from 24 to 12 , during which the system maintains full compensation by forcing
unity PF operation without occurrence of switching ripples in the supply current. e results conrm
the good performance of the compensator for a rapid change in the load current. us, the indirect cur-
rent control algorithm oers better response.
