| Abstract: | A new high power factor correction circuit is proposed. In this paper, two working modes of the circuit are introduced and compared in the analysis of the working principle of this circuit. Some calculation and emulation are also given in the paper, which prove that this circuit is with high power factor. Compared with the power factor correction circuit of boost, the proposed circuit has reduced switch stress so that the switch is not easily be damaged. Also the circuit is efficient , stabile and with simple structure. |
