Invention Reference Number
The growing demand for electric vehicles (EVs) has necessitated significant advancements in EV charging technologies to ensure efficient and reliable operation. Among various power conversion systems, bi-directional resonant converters have emerged as a pivotal component for enabling vehicle-to-grid (V2G) applications, which allow EVs to serve as energy storage units for the electrical grid. Despite their potential, the design of these converters often involves complex optimization processes and extensive reliance on voltage and current gain functions, which can be time-consuming and computationally intensive. To address these challenges, this invention introduces a novel design methodology for bi-directional series-series resonant converters. By employing simplified equations, this approach significantly reduces the complexity of the design process while maintaining critical operational criteria such as zero phase angle switching (soft switching) under maximum power output conditions. This advancement not only streamlines the design workflow but also enhances the converter’s performance and reliability in both charging and discharging modes.
