-This paper presents modeling, design and analysis of a bidirectional half-bridge DC/DC converter suitable for power electronic interface between the main energy system and the electric traction drive in hybrid electric vehicles. A solar based renewable energy system is considered as input. A parallel dc-linked multi input converter with a half-bridge bidirectional DC/DC cell topology is chosen...

In this paper, a new structure for buck-boost Z-source converter based on Z-H topology is proposed. The proposed converter consists of two LC networks similar to the conventional Z-source and Z-H converters. One of the characteristics of the proposed structure is that, without any changing in its’ power circuit, it can be used in different conversions such as dc/dc, dc/ac and ac/ac. This unique...

A monolithic CMOS voltage-mode, boost DC-DC converter with integrated power switches and on-chip pulse-width modulation (PWM) technique of switching control is presented in this paper. The PWM scheme used in this converter is constructed by a CMOS ring oscillator, whose duty is compensated by a pseudo hyperbola current generator to achieve almost constant frequency operation. The proposed boost...

The fuel cells are considered as one of the most promising devices for standalone/grid connected distributed generations (DGs) due to its cleanliness, modularity and higher potential capability. The barriers in the widespread use of fuel cells are their slow response for sudden load changes and higher installation cost. In this paper a simulation study of dynamic behavior of Nexa 1.2kW PEM fuel...

This paper presents the design and modeling of DC/DC boost (step-up) converter for Advanced Intelligent Systems using Matlab/Simulink. The steady-state and average-value models for the proposed converter are developed and simulated. This work offers modeling and simulation techniques to analyze and design for an overall efficiency optimization of standard synchronous and asynchronous boost conv...

Multichannel resonant DC/DC converters have recently been popular in diverse fields, where multiple output voltage levels are required, such as supplying multilevel inverters. This paper is devoted to present the new member of a four-channel converter family, having consisted till now step down well step-up/down configurations. The capable realizing power flow amongst two input and four channel...
