“…When a pulse waveform with a variable width, obtained through the application of sinusoidal pulse width modulation (SPWM) technique, is passed through filtering, it results in the generation of a sinusoidal waveform [133]. Improve the filtered sinusoidal waveform by increasing the switching frequency and adjusting the reference or modulating voltage's amplitude and frequency.…”

The state-of-the-art dynamic voltage restorers (DVRs) have advanced significantly in recent years. Modern DVRs can detect voltage sags or dips on the power line in real-time and are able to rapidly inject a compensating voltage to maintain a constant voltage at the load. This helps to improve the power quality of the electrical distribution system and to protect sensitive electronic equipment from voltage fluctuations. One key development in the field of DVRs has been the use of advanced control algorithms that enable the DVR to track the voltage more accurately on the power line and to inject a compensating voltage more accurately. These algorithms can be implemented using digital signal processors (DSPs) or field-programmable gate arrays (FPGAs), which allow for fast and precise control of the DVR. Another important development has been the use of high-frequency inverters in DVRs. These inverters can operate at much higher frequencies than traditional inverters, which allows them to switch on and off more quickly and to inject a more precise compensating voltage. This can help to further improve the power quality of the electrical distribution system. Overall, the state-of-the-art DVR technology continues to evolve, and new advances are being made all the time to improve the performance and reliability of these devices.

“…For three phase inverters, several modulations are employed, including space vector pulse width modulation (SVPWM) extending the linear modulation range by 15% more than SPWM. By infusing the tripled harmonics, the modulation range of THIPWM expanded [133].…”
