A comparative study on DC motor drive fed by synchronous SEPIC converter and synchronous Zeta converter

With the increase in the power demand and limited fossil fuels the renewable energy source plays a vital role to overcome these challenges. This paper presents a comparative study on DC motor drive fed by synchronous SEPIC and synchronous Zeta converter for stand-alone PV system. Both converters will operate either in buck mode or boost mode depending upon the availability of solar energy. The simulation is performed for separately excited DC motor using both converters using PSIM 9.3.
