DC-to-utility interface using sinewave resonant inverter

Abstract

A line-current modulated high-frequency (HF) link DC-to-utility interface power conditioning (DC/UIPC) system using a sinewave output resonant inverter is proposed. The proposed system consists of a sinewave output HF resonant inverter, a rectifier and a line connected inverter (LCI). The system is modelled using a constant current model for the HF inverter, and a Step model for the DC link current. The operating modes, analysis, design and experimental results are presented.
