| Abstract: | In order to solve the problem of narrow load range for the existing bridgeless power factor correction circuit t, A new current detection circuit is proposed. The proposed circuit consists of current transformer, control switches, rectification and inverting amplifier. Detailed analysis of the proposed circuit work principle, and build an experimental prototype. The experiment results show that the power factor can be guaranteed for more than 0.9.proposed method in 10% of rated load to full load. |
