Positive/Negative pulse charging technology of battery based on PFC-LLC topology
A new topology is proposed as battery charging system.The topology has three parts.The first part uses the one-cycle control method,it has a function of power factor control,it also can improve the power factor of the system.The second part use the LLC resonance technology,it can make the switch ZVS and the rectifier diode ZCS in the secondary side.The switching loss is reduced and the efficiency of the system is improved.The third part use a bi-directional DC-DC topology,it can achieve the Positive/negative pulse fast charging.The topology has been simulated in the MATLAB and PSIM,the power factor and the system efficiency have been improved..
