Design Of High Frequency Dynamic Wireless Charging System For Electric Vehicle

Dynamic Wireless Charging Technology(DWCT)has become a hot issue in domestic and foreign researches.It is a kind of Technology that can provide real-time power supply to electric vehicles in operation,extend the driving range of electric vehicles,and improve the convenience and safety of ChargingThis paper designs an efficient and energy-saving dynamic wireless charging and monitoring system based on magnetic coupling resonance,including road power supply equipment wireless charging road car and field power supply monitoring system(1)the road through the rectifier voltage regulator power supply equipment link to ensure stable operation of the system and the adjustment of the power,and through the double E class inverter voltage inverter into high frequency signal is passed to the coil,the inverter link delayed low speed drive chip to drive switch tube,control chip DSP and CPLD combination of the resonance frequency of the closed-loop adjustment,not only can realize frequency tracking,can realize soft switch control;(2)the wireless charging road adopts a special coil design and conducts a lot of simulation analysis and correction through Comsol finite element simulation software to ensure the stable operation of dynamic charging;(3)using a series of discrete along the electric vehicle driving road transmitter coil,this paper designs the magnetic field orientation method for cutting the transmitter coil switch,can reduce the unnecessary energy loss and magnetic pollution,(4)system using LabVIEW establish visual monitor interface,and set up wireless communication,on the road to the voltage and current power of the temperature field of wireless power supply equipment state parameters,such as real-time monitoring,and these parameters can be set.
