PROJECT TITLE :

Single-Stage Variable Turns Ratio High-Frequency Link Grid-Connected Inverter

ABSTRACT:

High-frequency link inverters with single-stage isolated isolation can now have multi-level outputs thanks to a new technology called the variable-turns-ratio high-frequency link inverter, which is described in this study. To enhance the quality of the current, the turns ratio of the transformer can be dynamically adjusted to produce five different output levels (2, 1, and 0). There are only a few auxiliary devices added to this structure, compared to the two-level high-frequency link inverter that was previously used, and the extra circuit runs at low frequency and the density is refined. A 1000-W prototype inverter is planned and built to test the output performance of a single-stage active clamped forward grid-connected inverter with a variable turns ratio using this technique. The suggested single-stage variable-turns-ratio high-frequency link grid-connected inverter is based on simulation findings and prototype tests.
