Universal Bridgeless Nonisolated Battery Charger With Wide-Output Voltage Range

Also Available Domains Electrical Vehicles

Project Code :TEPGPE271

Objective

The main objective of this project is to design a universal bridgeless non-isolated battery charger with a wide-output voltage range aimed to efficiently charge batteries from various sources.

Abstract

This paper proposes a new universal battery charger to charge EV batteries whose output voltage is ranging from 48 to 450 V. A dual-loop distinct current controller with a seamless transition for boost and buck operations is designed, which regulates the output voltage and maintains the unity power factor at the grid side. Furthermore, an active harmonic minimization method is incorporated with the designed controller to attenuate the prominent third-harmonic in the reference current and eradicate subharmonic oscillations. The performance of the proposed OBC is validated through the MATLAB simulations.

Keywords: — AC–DC power converters, battery chargers, electric vehicles, power converter.
