| Abstract: | In order to control the pollution of harmonic wave to power grid.it is necessary to add PFC module to the power supply.A boost converter module is implemented on the basis of active power factor principle,which can convert 90-264 V input AC voltage into 400 V stable output DC voltage.The L6561 is selected as the kernel control chip in the converter.The results prove that the converter can work with high output voltage stability and the power factor can reach over 0.94.The design can reduce the loss of power system. |
