Numerous engineering complexities are simplified using optimization algorithms. In a solar power system, the necessity of the voltage regulator is obvious. To control the regulator existent research works used PI, PID controllers that might have an unwanted transient response. To overcome such drawbacks here, a fresh scheme is proposed for the designing of the adaptive sliding mode (SM) controller of a solar powered LUO converter using optimization algorithms. The PSO ('Particle Swarm Optimization') is proved to expedite the convergence characteristic for many applications. Here, an ameliorated PSO version is developed. This algorithm is termed the Parameter Improved-PSO (PIPSO) algorithm. In this algorithm, the parameters, say, inertia weight, social along with cognitive agents is updated in every generation. The Proportional Integrator (PI) controller is used. The gain of this controller is tuned using the PIPSO. This algorithm's objective function is to lessen ISE ('Integral Squared Error') of the converter's output voltage. This parameter is picked as the objective function of the optimization algorithm. The proposed PIPSO is established to show better outcomes when contrasted to the traditional PSO concerning tuning a collection of parameters. An analysis is also made to evaluate the effect of usage of the solar panel () in the proposed work.

As contrasted to all other 'RE' sources (Mekhilef, et.al, 2011) the photo-voltaic (PV) energy has advantages such as no noise, cleanliness, along with very less maintenance. The PV (Sangwongwanich, 2018) systems are broadly used for low power electrical generation. This paper attempts to use non-RE as the voltage source input. The DC − DC conversion technology has evolved as a major area of research in the power electronics and drives field. DC − DC converters (Chen et.al, 2017), (Forouzesh et.al, 2017), (Riedel et.al, 2017) are nothing but electrical circuits which can transport the energy to a load. In such sorts of converters, the switches can either be diodes or transistors. The voltage value (transferred) relies upon the switches' duty ratios. The DC − DC converters are extensively utilized on industrial applications along with computers hardware circuits. A disparity of the PI-Derivative (PID) control that utilizes just the proportional and integral terms is called PI control. The PI is further widely utilized than the PID.
This paper presents a soft switching bidirectional buck-boost converter for battery charging and discharging systems. The proposed method comprises of Inductance Capacitance Diode combination of the bidirectional dc-dc converter with one more electric switch is presented to accomplish high efficiency, high conversion ratio and maximum output power compared to the other bidirectional converters. It works in both steps up and steps down conversions. The proposed converter has alleviated the switching stress problems in the conventional bidirectional dc-dc converter. It suppresses the switching losses by zero voltage and zeroes current turn ON and OFF all switches. The complete steady-state analysis of the proposed bi-directional converter has described with its operating modes. Design consideration of parameters also presented to realize the converter characteristics. The switching stress on the power semiconductor devices is given, and the comparisons between the proposed technique and other bidirectional converters are illustrated with some results. Finally, the experimental prototype of 20 kHz, 315 W output power converter developed, and its feasibility verified through computer simulation results.
In this paper, a novel cascaded multilevel inverter is being proposed without using a full bridge inverter module. By arranging the input dc sources in a proper sequence, this proposed system eliminates the role of the full bridge inverter module. This paper is mainly focusing on the number of power switches used in order for the particular level output. The main advantage of this proposed model is its simplified structure which leads the proposed structure to be more compact. Two different input voltage patterns have been described here for the proposed scheme. For each voltage pattern, different voltage output levels are obtained. The output voltage level can be increased effectively by choosing the proper input voltage magnitude. It uses only the asymmetrical mode of configuration. Its simulation and experimental results verify the operation and performance of the proposed system. Finally, the comparative analysis has been made with some recently developed topologies to ensure the effectiveness of the proposed system.
