TY - JOUR AU - Suman, Swati AB - In this research, an improved reduced multilevel inverter (MLI) design with a single active voltage source and the lowest possible power switches is proposed. Asymmetrical voltage sources power this reduced MLI using series capacitors connected to a single photo voltaic (PV) module. Due to the use of a minimal number of switching devices and input voltage sources, this MLI design also can be appropriate for integrating PV sources with low voltage grids. The constraints of the cascade H-bridge MLI and traditional two-level inverter have been overcome by the offered approach due to low switching loss and minimum switching stress. The variable capacitance ratio with respect to a reference value and the required switching pulses is calculated using a new metaheuristic technique called red deer optimisation (RDO) algorithm. The total harmonics distortion (THD) of the MLI output voltage has been reduced by this technique to 3.52%. To demonstrate the usefulness of the RDO method, its performance was compared to that of particle swarm optimisation (PSO) and Grey Wolf optimisation (GWO). In addition to simulation and experiment, the usefulness and productivity of this reduced MLI have been supported by these results.
