| Abstract: | It is an effective method that active power factor correction converter is added in order to reduce the power harmonic pollution to power network.The operating principle of the converter based on NCP1608 is discussed.The design of the boost inductor is given and the key practical techniques are introduced.Experiment results show that the power factor is great than 0.96 in the input range of AC90~265V and the converter is very practical. |
