“…By using the voltage lift technique, Luo converters can achieve significant voltage gain, but at the same time, topological complexity, cost, volume, and losses rise [4][5][6]. Despite the complexity of their operating mode, converter construction, and control technique, interleaved configurations can attain wide step-down or step-up voltage conversion ratios with minimum voltage stresses [7][8][9][10].…”

A feature known as high-voltage gain conversion is necessary for a number of applications, including photovoltaic (PV) connected systems, UPS, SMPS, and some inverter applications, specifically for the power processing of low-voltage renewable sources. This article makes a suggestion for an ultra-gain boost converter based on a switched-inductor switched-capacitor (SISC) network. Ultra-voltage gain (> 15) and lower voltage stresses across the switches are the main benefits of the proposed converter. Additionally, compared with other high-gain topologies, the number of components decreases. This paper presents a systematic analysis of the proposed ultra-gain boost DC–DC converter along with a comparison to other topologies that have been previously published in the literature. The simulation model confirmed that the efficiency of the proposed topology is 95.23%.

“…This stabilizing input voltage of the inverter can provide fewer harmonics to the motor, which can improve the lifetime of the motor as compared to high harmonics which improves the reliability [11,12] and continuous availability of power supply of the drive. The problem of long-term interruptions in the power supply is addressed by integrating renewable energy sources (RES) with the DC-link [13,14]. The Photovoltaic (PV) generation method, which converts free solar energy into usable electricity through the photovoltaic effect, is one of the most widely utilized RES.…”

The motor drives for aqua farms and large-scale irrigation system needs a reliable electric drive, which requires the continuous power supply and efficient control. However, the rural single phase power supply is frequently interrupted. Renewable assistance would improve the availability of supply and heuristic control approach improves robustness in control. This paper presents a three phase induction motor drive fed from single phase electric grid with assistance from PV and battery energy storage. TS- fuzzy based direct torque control is employed for robust control during load changes, and the topology, component modelling, front-end converter control, PV interface DC–DC converter control, and inverter control are presented. MATLAB/Simulink is used to simulate the proposed drive system. The performance of the proposed system is validated using simulation data for both steady-state and transient states.

“…In Conventional ac/dc converters normally consists of two stages, first stage performs the PFC operation and at second stage is Dc-Dc regulator. Based on this, different converters are designed to achieve unity input current, high efficiency and to get less input current percentage (%) THD [5][6][7].…”

A novel single-stage single-switch isolated converter is proposed for attaining high power factor and wide voltage conversion range. This converter interfaces a buck-boost type PFC circuit with a buck type Dc-Dc regulator to process the input power in a single step. By this integration, the proposed converter is able to attain unity input power factor, wide voltage conversion range, low switching voltage stresses and high efficiencies. By isolating the converter non-inverted output voltage is obtained which is an advantage over non-isolated topologies. The input buck-boost stage is operated in discontinuous conduction mode (DCM) to attain high input power factor and the output buck stage is operated in continuous conduction mode (CCM). A simple single closed loop voltage feedback controller is used to get well-regulated and fast output voltage response. A detailed principle operation and design of converter has been analysed theoretically. The performance of the proposed converter is simulated by using MATLAB-SIMULINK software to validate the simulation results with the experimental results.
