Maximum Energy Transfer Efficiency in Solar-Powered Bilateral Dual-Stage AC to DC Converters for Vehicle-to-Home and Vehicle-to-Grid Applications

Transition to alternative sources of energy is essential to halting global warming and lessening its effects on biodiversity. In this research, the beneficial environmental effects of integrating powered by solar energy multiple stage bidirectional AC to DC converters in Vehicle-to-Home (V2H) and Vehicle-to-Grid (V2G) systems are investigated. By enabling efficient energy transmission between electric vehicles (EVs), the grid, and household energy systems, these converters enhance the handling of energy and long-term sustainability. Due to its simple construction and customizable properties, 2 stages isolated AC/DC converters are frequently employed in the rapidly expanding renewable energy vehicle industry. Here, we construct and assess a highly effective dual-stage in-car charger that operates effectively across a broad voltage range for both I/P and O/P. The main portion comprises PFC (power factor correction) converters with bridgeless buck-boost completely soft switching design, while the battery end converter is powered by an isolated filter-in-built direct current converter. The primary stage’s principal benefit is the elimination of electromagnetic interference (EMI) caused by sudden voltage fluctuations by creating an I/p and O/P common ground. This lessens the requirement for EMI filtering in common mode. Both the common mode (CM) noise and the total leakage current are maintained at a reasonable level. Greater efficiency and power density are the main advantages of the second stage. In order to make sure the safe charging and discharging of batteries, a converter that offers controls battery current and galvanic isolation is needed.
