The solid state transformer (SST) has emerged as a pivotal technology in modern power electronics, offering superior performance compared to conventional transformers through advanced semiconductor switching techniques. This paper presents a comprehensive review of soft-switching solid state transformers, examining their operational principles, topological configurations, control strategies, and practical applications. The integration of soft-switching techniques in SST designs significantly reduces switching losses, electromagnetic interference, and thermal stress while improving overall system efficiency. Through detailed analysis of various soft-switching methodologies including zero-voltage switching (ZVS) and zero-current switching (ZCS), this research highlights the technological advancements that have made SSTs viable for high-power applications. The paper also addresses the challenges and future prospects of soft-switching SST technology in the context of smart grid integration and renewable energy systems.
