Abstract

This paper presents a bi-directional CLLC resonant converter for Energy storage Systems applications, with an integrated planar transformer to enhance power density and curtail the parasitic elements in the transformer. The passive elements in any converter account for the bulkiness, and it can be vanquished by increasing the switching frequency, which can only be entailed by a planar magnetic structure and wide band-gap devices like gallium nitride (GaN) and silicon carbide (Si). Further, FEA analysis is performed to estimate leakage, AC resistance, and core losses for an integrated planar transformer. A simplified voltage/current loop control is implemented on a 32-bit digital signal processor (TMS320F28379D) for battery charging. The advantage of the proposed transformer design is validated through a 300-350 kHz, 500-750 W CLLC resonant converter with a peak efficiency of 96.60%
