Abstract
The availability of an uninterrupted power supply to loads is an important aspect of power system reliability and resiliency. With rising natural and human-made power system disruptions, the necessity for alternative renewable-based sources is becoming increasingly important. This article outlines a unique and efficient photovoltaic (PV) system design for a standalone application that keeps critical loads continuously powered in case of any grid power outages. The PV system proposed here uses a Cross T-Type multilevel inverter (CT-Type MLI) and single input multiple output (SIMO) DC–DC converter. The CT-type MLI improves overall system performance based on total harmonic distortion (THD), number of levels, number of components required, total standing voltage (TSV), cost factor per level, and efficiency. Moreover, the presence of an isolation transformer in the DC–DC converter eliminates the need for a bulky power transformer on the AC side of the converter, making the system more economical for grid integration. It also allows DC-link voltage to be bucked/boosted as per requirement.
