N2 - This paper presents a single-phase bidirectional isolated AC/DC converter, which is composed of a half-bridge composed of bidirectional switches on the primary side and a full-bridge composed of ordinary MOSTST on the secondary side. It can realize the function of single-stage power conversion. The converter adopts a control scheme combining phase shift and frequency modulation to realize the AC/DC conversion function on the premise of realizing zero voltage switching (ZVS). This essay first analyzes the operation mode of the proposed topology, then discusses the conditions required to implement ZVS, and then makes a simple analysis of the reliability of the entire topology. Finally, the simulation parameters and the simulation waveforms of the proposed topology under two operation modes are given.
