Plug-in hybrid electric vehicles (PHEVs) are equipped with a high energy density battery pack, which should be externally charged form the grid. This requires a high power battery charger circuit which can operate at universal input voltage and be capable of maintaining the required output voltage and current with low ripple. The topology composed of PWM boost rectifier cascaded with a bidirectional...
A novel power converter for battery used in the Plug-in Hybrid Electric Vehicle (PHEV) is proposed, which could charge and discharge the battery effectively. The system is composed of two parts: a three phase full bridge PWM rectifier and a DC/DC converter. The PWM rectifier is utilized to rectify the three phase AC to DC voltage, which should be higher than the battery terminal voltage. The DC/DC...
We are considering the problem of controlling AC/DC switched power converters of the buck-boost type. The control objectives are twofold: (i) regulating the output voltage to a desired reference value, (ii) assuring a unitary power factor by enforcing the voltage and the current delivered by the electric network to be in phase. The considered problem is dealt by designing a cascade-structure nonlinear...
