Transformerless Dynamic Voltage Restorer based on Switched Capacitor Multi Level Inverter and Interleaved Boost Converter

This paper aims to address power quality issues by proposing a transformerless Dynamic Voltage Restorer (TDVR) concept, this research seeks to overcome problems with power quality. A power electronics device called a DVR injects voltage in series with the supply to protect delicate loads from voltage and current fluctuations. To address voltage issues and reduce harmonics, the suggested model includes switched capacitor multilevel inverter (SCMLI) and an interleaved boost converter(IBC). A hardware implementation employing a low-voltage DVR prototype is also carried out to monitor output voltages and analyse Total Harmonic Distortion (THD) results during voltage sag and swell occurrences. This project's ultimate goals are to improve electricity quality, raise dependability, and decrease costs within the distribution grid.
