High Efficiency Electric Vehicle Battery Charging System Using MCPWM and PSO Technique

The charger plays a very important role within the development of electrical vehicles (EVs) and plugin hybrid electrical vehicles (PHEVs).This thesis focuses on the DC-DC device for prime voltage charger and is split into four chapters. The background associated with EV battery charger is introduced, and therefore the topologies of isolated DCDC device presumably applied in battery charge square measure sketched in Chapter one. Since the EV charger is high voltage high power, the phase-shifted full bridge and LLC converters, that square measure popularly utilized in high power applications, square measure mentioned intimately in Chapter two. The typically thought-about as high efficiency, high power density and high dependability, however their distinguished options are restricted in sure vary of operation. to form full use of the benefits and to avoid the limitation of the phase-shifted full bridge and LLC converters, a completely unique hybrid resonant and PWM device combining resonant LLC half-bridge and section shifted full-bridge topology is projected and is described in Chapter three. The device achieves high potency and true soft switch for operation vary, that is incredibly necessary for prime voltage EV charger application.
