Design of an 11 kW power factor correction and 10 kW ZVS DC/DC converter for a high-efficiency battery charger in electric vehicles

In this paper, a single switch single stage switched inductor based cuk converter with power factor correction control techniques is proposed. The main features of the proposed converter is low current stress, high voltage conversion ratio, reduction of components, high efficiency, low THD, etc., The operation of the proposed converter is explained in several modes along with the design of the converter. The performance of the proposed converter with different loads such as resistive, battery and motor loads with CC and CV control is analyzed and various factors such as power factor, efficiency and THD are compared. The Simulation work is carried out in MATLAB/Simulink software.

Recovery Problem

This paper presents a new battery charger for low power electric vehicles with high power factor and Efficiency. The main objective of the proposed design is to reduce the conduction losses and Reverse Recovery Problem in power diodes. To eliminate both the issues, the diode rectifier is present in primary and secondary side of the transformer an series resonance circuit added. By using the series resonance circuit, Zero Current Switching (ZCS) possible and also alleviates the reverse recovery problem. Thus the proposed new battery charger operates with high power factor and high efficiency. Additionally, by using the present single power conversion, it is easy to install the on-board charger in the EVs. After the theoretical analysis, Simulation Results are obtained on MATLAB/Simulink environment and Hardware results are from the proposed model.
