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. The performance and properties of sliding mode controller is compared with Proportional Integral Derivative (PID) controller and Proportional Integral (PI) controller. Simulation results shows th...

Fuel cells are new alternative energy resource that has a great promise for distributed generation and electric vehicle application. However, fuel cells have a slow response due to their slow internal electromechanical and thermodynamic response. To optimize the fuel cell system performance, a fuel cell DC-DC converter with an appropriate controller which can regulate the power flow and automat...

This paper deals with bifurcation analyses in current programmed DC/DC Boost converter and exhibition of chaotic behavior. This phenomenon occurs due to variation of a set of the studied circuit parameters (input voltage and a reference current). Two different types of bifurcation paths have been observed as part as part of another bifurcation arising from variation of suitable chosen parameter...

DC-DC power converters with multiple inputs and a single output are used in numerous applications where multiple sources, e.g., two or more renewable energy sources and/or a battery, feed a single load. In this work a classical boost converter topology with two input branches connected to two different sources is chosen, with each branch independently being controlled by a separate peak current...

A simple step and search control strategy for extracting maximum output power from grid connected Variable Speed Wind Energy Conversion System (VSWECS) is implemented in this work. This system consists of a variable speed wind turbine coupled to a Permanent Magnet Synchronous Generator (PMSG) through a gear box, a DC-DC boost converter and a hysteresis current controlled Voltage Source Converte...

this brief introduces a method of improving the power conversion efficiency of a dc-dc boost converter with passive snubber circuit. This method uses a passive snubber circuit which consists of two inductors, a capacitor, and a diode, to reduce switching loss. The use of passive soft switching methods has been emphasized as better alternative to active methods mainly because they do not require...

This Paper introduces new hybrid converter topologies which can supply simultaneously AC as well as DC from a single DC source. The new Hybrid Converter is derived from the single switch controlled Boost converter by replacing the controlled switch with voltage source inverter (VSI). This new hybrid converter has the advantages like reduced number of switches as compared with conventional desig...

-In this paper, comparative evaluation of different techniques for harmonic reduction in input current of ac-dc converter is presented. Converters employing ac side switching, resonant converter, active clamped boost converter are simulated in PSIM and their performance under varying load condition with load voltage regulation is evaluated.

This project is a highly efficient and novel control strategy for improving the transients in the output voltage of a dc–dc positive buck–boost converter which is required for low-power portable electronic applications. The proposed control technique can regulate the output voltage for variable input voltage (higher, lower, or equal to the output voltage). There are several existing solutions t...
