The objective of this paper is to propose a three input boost converter for the hybrid system in order to simply the power system reduce the cost. The proposed converter having two source act as a input and third source act as a storage element. Supplying the output load, charging or discharging the battery can be made by the PV and the wind power sources individually or simultaneously. The pro...

Distributed generation is an emerging concept in the electricity sector, which represents good alternatives for electricity supply instead of the traditional centralized power generation concept. Among different distributed generation schemes, fuel cell is expected play a big part due to its inherent advantages. The power density of the quasi-Z-source-based single-phase isolated DC/DC converter...

This thesis aims to identify and analyze the nonlinear behavior in the threephase voltage source converter, which is widely used as an interface converter in a distributed hybrid power system (DHPS). In this system, the converter does not work as a standalone converter but operates as a subsystem that connects to a non-ideal power grid and interacts indirectly with other subsystems via a point ...

Software industry has a huge amount of legacy programs needing modernization and re-engineering. We are especially interested in re-engineering legacy programs via language conversion. In language conversion, the source and target languages can be either from the same programming paradigm or from different ones. Thus, we consider program modernization from two aspects. If the source and target ...

This paper presents first an overview of the wellknown voltage and current dc-link converter topologies used to implement a three-phase PWM ac–ac converter system. Starting from the voltage source inverter and the current source rectifier, the basics of space vector modulation are summarized. Based on that, the topology of the indirect matrix converter (IMC) and its modulation are gradually dev...

This paper introduces a novel two transistors forward topology employing a z-source to achieve ZVZCS and power transformer resetting for various applications. Comparing with the forward converter, this topology has the advantage of displaying ZCS condition with an added Z-Source and no additional switches when the switches turn on, and that ZVS condition happens when the switches turn off. Duty...

Abstract: This paper proposed a new type of converter called Single Phase Switched Inductor Z-source Matrix Converter (SLMC). It is an ac-to-ac converter with diode bridge bidirectional switch cell. The limitations of existing matrix converter like voltage regulation and quality output issues are overcome in the proposed SLMC by adding the switched inductance. The simulation is performed for di...

34 Abstract— This paper presents an analysis of the dynamic performance on DC-DC SEPIC (Single Ended Primary Inductor Converter) converter which is operating in continuous conduction mode (CCM) with PID and fuzzy logic controller implementation. The operational analysis and design is done for 20W load. SEPIC converter is a suitable converter when the input voltage has got wide variations around...

This paper proposes a new two-stage inverter based on transformer-less high gain DC-DC converter for energy conversion of a photovoltaic system. The designed system consists of a high gain DC-DC converter cascaded with a three-phase inverter. The proposed DC-DC converter has a simple structure, and it has one switch in its structure. The output voltage of the DC-DC converter supplies DC source ...
