<p><em>The utilisation of power electronic equipment in the system generates different types of harmonics. These reduce the efficiency, reliability, and safety of the equipment. It is mandatory to reduce voltage and current harmonics to the level as per international standards of IEEE 519 and IEC 61000. The standards also specify limits of voltage and current harmonics, and they have to be measured in terms of % Total Harmonic Distortion (%THD). As per IEEE-2022, the voltage harmonics should be &lt; 5% THD for nominal voltages of ≤ 69 kV and current harmonics &lt;8% THD for ISC/IL (maximum short-circuit current/fundamental frequency load current at PCC, ratio between 20-50). The harmonics present in the system are odd, even, triplen, and interharmonics, with respect to the fundamental frequency of 50 or 60 Hz. There are various methods to limit these harmonics to the level required by standards. These are harmonic filters. The types of filters available are shunt, series, passive, active, and hybrid active filters, the usage of which will depend on the type of power electronic equipment used in the system. This paper discusses the various harmonic frequencies present in the system and which methods to adopt to bring them to the level accepted by the standards. A pilot plant is taken up for investigating the level of harmonics present and the methods adopted to bring them to the accepted level.</em></p>

<p><em>As light electric vehicle (LEV) charging infrastructure increasingly supports 400 V/800 V battery platforms, power-dense bidirectional converter architectures have become an important research subject. This paper provides a review of resonant and boost converter topologies for LEV on-board charging applications and a synthesis of peer-reviewed publications from 2024 to 2026 that examine efficiency, power density, wide voltage gain regulation, and bidirectional power flow. The review lays the theoretical groundwork of boost conversion and the LLC/CLLC resonant-tank behavior, and it synthesizes the literature into six cross-cutting themes. Wide-bandgap semiconductors combined with zero-voltage switching and resonant topologies consistently achieve efficiencies of 97% or higher, and integrating several discrete passive components yields significant power density benefits. For an extended voltage gain range with an unchanged semiconductor count, single-stage architectures face greater difficulty in meeting dynamic regulation requirements, and reconfigurable or morphing resonant-tank strategies have become the most widely accepted approach. The review also outlines persistent open issues, which are summarized as a prioritized research agenda: extended prototype scaling beyond laboratory power levels, analysis of 400 V/800 V platform compatibility, and consolidation of the parameters and equations required to define and analyze integrated magnetics.</em></p>
