This paper presents the design and simulation of the zero voltage zero current switched non isolated dcdc boost converter. Many applications powered by batteries need high performance, high step up dc-dc converters. When the converter switches are turned on and off at high frequency to meet dynamic and steady state requirements, the losses add on in the converter. When current through the switc...

This paper explores a configuration for boost half bridge DC-DC converters, connected in parallel at the input and series at the output, such that the converters share the input current and load voltage equally. A stable control scheme has been developed to achieve this objective. In order to verify the effectiveness and stability of control scheme, input-parallel output-series (IPOS) connected...

This paper presents a new single stage DC-DC multilevel boost converter topology with very high voltage gain ratio. It is a Pulse width modulation (PWM) based switched inductor multilevel boost converter (SIMLC) consisting of two switched inductors, 2N+2 Diodes, 2N-1 Capacitors for N level boost converter. High switching frequency has been used to decrease component size. The proposed converter...

The connection between PEM fuel cells and common DC-DC converters is examined. The analysis is model-based and done for boost, buck and buck-boost converters. In a first step, the effect of the converter ripples upon the PEM fuel cell is shown. They introduce oscillations in the fuel cell. Their appearance is explained, discussed and possibilities for their suppression are given. After that, th...

The DC-DC boost converter reveals highly non-linear and non-minimum phase properties, is very difficult task to design a controller that is healthy against load variation. For this purpose a Fuzzy PID Controller is proposed to control DC-DC boost converter which has a practical inductor and a series resistance. A balancing ProportionalIntegral-Differential (PID) controller to the parallel-dampe...

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.

In this paper, a non isolated multi-input multi-output dc–dc boost converter is proposed. This converter is used to implant alternative energy sources in electric vehicles. However, advantages of different sources of energy are achievable by the implant energy sources. This converter has many outputs with different voltage levels, which can be interfaced with multilevel inverters. In this conve...

In this study, an integrate modeling and controlling of DC-DC boost converter topology is proposed. The traditional DC-DC boost converter topology has the major drawback such as the input power supply is an unregulated rectified voltage and the load on converters is affecting the effectiveness of the converter. The proposed boost converter topology is differed from the traditional boost convert...

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...
