Raja Sekhar Reddy 02 03 A simulation technique examined the quality output of a single phase PWM pulse width modulated voltage source inverter incorporated with seriesparallel resonant inverter configuration The output voltage and current harmonic contents helped evaluate the inverter performance both with and without filter implementation Researchers have designed and tested two variations of single phase PWM inverter with an evaluated LLCC seriesparallel filter The inverter requires an RMS value controller as its subsequent element to secure steady output signals The proposed work yields beneficial effects on inverters that need minimum THD percentages alongside highquality AC output Copyright (c) Journal of Science Engineering Technology and Management Science.
