Analysis and design of a high-frequency link DC to utility interface using square-wave output resonant inverter

A line current modulated high-frequency (hf) link dc to utility interface power conditioning system using a square-wave output resonant inverter is proposed. The proposed system consists of a square wave output hf resonant inverter, a rectifier and a line connected inverter. The system is modeled using Constant current model for the high-frequency inverter and Step model for the dc link current. The operating modes, analysis, design and experimental results are presented.
