Power Factor Correction by ANN Based Bridgeless Modified Landsman Converter

An increased power factor (PF) frontend battery is used to design a new Electric Vehicle (EV) charger in this paper. In general, Diode Bridge Rectifier (DBR) is used for generating current with low harmonics, but due to its excessive conduction loss, a Modified Landsman converter is established. Power Factor Correction (PFC) is recommended using a Landsman converter with a Bridgeless (BL) architecture for low power applications. The proposed converter solves various Power Quality (PQ) issues like, fluctuations, harmonics, device stress and current ripples. In the proposed work, EV battery which is a non-linear load causes PQ troubles on the input side resulting in input supply deterioration. To make the supply stable, the suggested converter adopts an Artificial Neural Network (ANN) controller. The minimized error from the ANN controller is fed to the PWM generator through which the distortions gets eliminated and a stabilized supply with unity PF operation is obtained. The entire work for enhancing PQ through Bridgeless Modified Landsman Converter (BLML) is carried out in MATLAB and simulation responses are obtained.
