This paper presents a simulation model of the electric part of a grid connected photovoltaic generator. The model contains a detailed representation of the main components of the system that are the solar array, boost converter and the grid side inverter. A proper control of the DC/DC converter is developed in order to extract the maximum amount of from the photovoltaic generator. The grid inte...

Conventional energy sources are fast depleting due to poor conservation practises and excessive usage while the world’s energy demands are growing by minute. Additionally, the cost of producing conventional energy is rising also leading to an increase in harmful environmental pollution. Hence, there is a need to look at alternative energy sources such as sun, water and wind. Photovoltaic (PV) i...

Abstract – This document gives you a brief idea of the Design and simulation of DC/DC Boost converter operating in continuous conduction mode using pulse width modulation based sliding mode controller.

Received May 20, 2012 Revised Aug 20, 2012 Accepted Aug 26, 2012 Design and simulation of a simple power electronic interface for gridconnected PV array has been proposed using boost converter and linecommutated inverter with maximum power point tracking (MPPT) controller. The output of PV array varies with irradiation, and hence the duty cycle of the PI controller is adjusted automatically to ...

In this paper, we propose a new technique used to design a robust controller that is not as high-order and complicated as the ones designed by conventional Η∞ loop shaping method. To overcome the problem we proposed an algorithm called Genetic Algorithm (GA) based fixed-structure Η∞ loop shaping control. In the approach, GA is adopted to solve the Η∞ loop shaping design problem under a structur...

DC–DC step-up converters for high-output voltage applications typically demand high voltage devices, leading to high conduction and switching losses. This identified demand has motivated research on active clamping and multi-level topologies. On this context, this study presents the study of a novel DC–DC boost converter with three-level boost-type active clamping, zero-voltage switching (ZVS) ...

Renewable energy sources and in particular Photovoltaic (PV) system are implemented in large scale in many countries for power generation. The characteristics of PV arrays are non-linear i.e., the change in temperature and irradiation levels results in change of power generated by the PV arrays. DC-DC converters are connected between the PV system and the load as power conditioning unit to regu...

In this paper, a discontinuous conduction mode (DCM) frequency control algorithm is proposed to reduce the input current ripple of a multi-phase interleaved boost converter. Unlike conventional variable duty and constant frequency control, the proposed algorithm controls the switching frequency to regulate the output voltage. By fixing the duty ratio at 1/N in the N-phase interleaved boost conv...
