Design of PFC with Buck Boost Converter for Plug- In Electric Vehicles and Battery Charging Applications

Abstract

The wireless charging system working principle is same as transformer. It consists of transmitter and receiver, the AC supply is converted into high frequency alternating current, which is supplied to transmitter coil. Then it produces an alternating magnetic field which cuts the receiver coil and the receiver coil generates AC power output. The important thing in the wireless charging system is to maintain the resonance frequency between transmitter and receiver in order to make it effective. With the high modernization and electrification of industry, people now have a higher requirement for the power quality. For instance, personal computers, electronic devices, cell phones, they each has a basic requirement for power quality. Because of the wide application of power electronic devices, there are reactive power and harmonics in the power grid. The main research content of this paper is the design of boost power factor correction circuit and design of its control system. So we can conclude that the existence of harmonic current pollute power grid so much and we have to take some actions to eliminate or restrain harmonic current.
