Résumé: DC power supplies are extensively used inside most of electrical and electronic appliances such as in computers, televisions, audio sets and others. And the electrical energy available in the utility grid is not suitable for direct use. So in particular, applications requiring DC source must involve an interface device between the AC power line and the load requiring the DC voltage. Conventional AC/DC conversion involves diode rectifiers with large capacitor to reduce DC voltage ripple. The filter capacitor reduces the ripple present in the output voltage but draws non sinusoidal line current which reduces the power factor. Therefore, power factor correction (PFC) techniques are gaining increasing attention. This project introduces one of the most popular topologies for active PFC which use a boost converter to draw a continuous input current. This input current can be manipulated by average current mode control technique. But there is ripple in the input current due to inductor of boost converter, this can be minimized by using two phase interleaved boost converter. This project applied the average current mode technique to control two channels interleaved boost converter in continuous conduction mode using PI controller. The simulation results show that the applied topology provides high power factor and low THD.
