Abstract:
Renewable Energy Sources (RES) such as PV modules, fuel cells deliver output voltage with a high voltage gain converter is essential for the following reasons, such as to maintain high step up voltage, with good output voltage profile with respect to sudden changes in BLDC motor drive. This paper presents the high performance of fast charger for a lithium-ion electric vehicle propulsion battery with PV source. The device is intended to operate in a battery switch station, allowing an up-to 1-h recharge of a 25-kWh depleted battery, removed from a vehicle. The charger is designed as a dual-stage-controlled ac/dc converter. The input stage consists of a three-phase full-bridge diode bridge rectifier combined with a reduced rating of shunt active power filter. The input stage creates an uncontrolled pulsating dc bus while complying with the grid codes by regulating the total harmonic distortion and power factor according to the predetermined permissible limits. The output stage is formed by six interleaved groups of two parallel dc-dc converters, fed by the uncontrolled dc bus with BLDC drive and performing the battery charging process. The charger is capable of operating in any of the three typical charging modes: constant current, constant voltage, and constant power. Extended simulations are shown to demonstrate the functionality of the device.
