| Abstract: | The neutral wire is introduced and connected to a full bridge three phase AC/DC converter to get a novel topology for PFC In this topology,isolation of the DC output from AC input is achieved because of the full bridge Softswitching is obtained with phase shift technique The PFC principle is analyzed and the power factor is about 0 98 Pspice is used to simulate the topology It is shown that the higher the rectified voltage is,the higher the power factor is Some experimental results are given |
