In this paper, the current feedback method is presented to control the low frequency oscillation in one-cycle-controlled Boost converter to operate in period-1 state. The stroboscopic map of the one-cycle-controlled Boost converter with current feedback is obtained by using the data-sampling method. Based on the presented stroboscopic map and the help of the loci of eigenvalues of the Jacobian matrix, the stable range of feedback gain is obtained. Finally, the results of simulation and experiment confirm the correctness of the theoretical analysis and the validity of the proposed method.
