In recent years, high-quality power becomes a prerequisite for research and industrial applications to ensure the results to be qualitative and the evaluation to be precise. To comply, all the sensitive equipment require high-quality power, where uninterruptable power supplies are merely used which guarantee continuous power supply to those loads. Inverter plays a major role in the UPS system. In this paper, the inverter of UPS is replaced by nine-level modified multilevel inverter (MLI) with the reduced number of switching devices and with equal voltage sources in order to that reduces the switching losses and harmonics. This proposed system is dealing with the strategy for PV applications using modified perturb and observe algorithm (MPO), so the maximum power is obtained at all time with reduced power oscillation. The voltage from the PV panel is very less that is boosted using DC–DC boost converter circuit and further fed to the inverter unit. In this system, the converter and MPPT control unit are formed into a closed loop so that the boost converter output depends upon the power obtained from the PV array. The proposed system model is developed by using MATLAB/Simulink software. Hence, the investigations done on simulation disclose that the proposed system affects a high output voltage with a very low total harmonic distortion using fewer switching devices.
