The growing demand for efficient high-power switching power supplies has spurred interest in advanced topologies. The three-phase VIENNA converter stands out for its high power factor, simplified structure, and robust performance. Current research focuses on its operational principles, control strategies, and behavior under various load conditions. Key considerations include component selection, thermal management, and EMI/EMC optimization. This topology finds applications across renewable energy systems, industrial equipment, telecommunications, and electric vehicle charging infrastructures. Comparative analyses with alternative topologies and cost-benefit evaluations are also addressed. Future developments are expected to emphasize the integration of wide-bandgap devices and advancements in digital control techniques to further enhance efficiency and system performance.
