This paper proposes a novel high step-up converter with an average mode control which is designed for power generation applications. The detailed steady-state analysis for the system is presented. According to the steadystate analysis, transfer functions of input voltage versus output voltage and duty cycle versus output voltage are obtained. In addition, some simplifications and design rules are proposed to facilitate the design of the feedback loop. The Sheppard Taylor Converter was primarily designed to provide non pulsing input and output current similar to the Cuk Converter, The energy of the cuk converter is bidirectional, but the sheppard taylor circuit trand former works is forward. The converter has two inductors that can shape the input current feed the output load, reduce the input and output current ripple. Compare to the cuk converter, the sheppard taylor converter can regulate output voltage with less variation in the duty cycle. Sheppard Taylor converter, state space averge model, high step up converter. High voltage gain DC-DC converters find its applications mainly in renewable energy integration.

“…Harmonic elimination is treated as an optimization problem that may be solved using a variety of evolutionary techniques [9][10][11][12][13] such as Genetic algorithms (GA), Particle swarm optimization (PSO), and Teaching-Learning based optimization (TLBO). But still, we authors find scope for improvement in the power quality.…”

“…The results illustrate that the suggested firefly algorithm can remove specific harmonics in a multilevel inverter's output voltage. To reduce THD in the inverter, [10,12] recommended a particle swarm optimization strategy and [11,12] suggested a Genetic Algorithm approach. Soft computing strategies have been shown to be successful in lowering the THD of a multilayer inverter in Teaching Learning-based optimization [13].…”

High-quality electrical energy is the most needed thing for standard living. We use power electronics converters for the conversion of different forms of electrical energy and we use them for producing quality power output. We use semiconductor devices as switches in the process of conversion of DC-DC, AC-DC, AC-AC, and DC-AC according to the requirement of the system. In this paper, an attempt is made to analyze the quality of output power from a multilevel inverter which is used in the conversion of DC supply to AC output voltage. Production of quality power by optimizing the multilevel inverter switching using Whale Optimization Algorithm helps the proposed inverter topology to perform well. The suggested topology and the optimization technique will help in harvesting multiple renewable energy sources with improved quality of power. Different DC sources of different voltage levels could be connected in input and the resultant AC output has less ripple content as per the IEEE standard. A detailed comparison has been made to show the superiority of the proposed algorithm.

Electric ships have been developed in recent years to reduce greenhouse gas emissions. In this system, inverters are the key equipment for the permanent-magnet synchronous motor (PMSM) drive system. The cascaded insulated-gated bipolar transistor (IGBT)-based H-bridge inverter is one of the most attractive multilevel topologies for modern electric ship applications. Usually, the fault-tolerant control strategy is designed to keep the ship in operation for a certain period. However, the fault-tolerant control strategy with hardware redundancy is expensive and slow in response. In addition, after fault-tolerant control, the ship’s PMSM may experience shock and overheating, and IGBT life is reduced due to uneven switching frequency distribution. Therefore, a stratified reconfiguration carrier disposition Sinusoidal Pulse Width Modulation (SPWM) fault-tolerant control strategy is proposed. The proposed strategy can achieve fault tolerance without any extra hardware. A reconfiguration carrier is applied to improve the fundamental amplitude of inverter output voltage to maintain the operation of the ship’s PMSM. In addition, the available states of faulty H-bridge are fully used to contribute to the output. These can improve the life of IGBTs by reducing and balancing the power loss of each H-bridge. The principles of the proposed strategy are described in detail in this study. Taking a cascaded H-bridge seven-level inverter as an example, simulation and experimental results verify that the proposed strategy, in general, has a potential future application on electric ships.
