Simulation of Combined Boost Converter Behavior with Positive Output Voltage and Investigation of Voltage Ripple at Output

In this paper, the behavior of a hybrid back-boost converter with a positive output voltage is simulated. This converter consists of an amplifier voltage converter called KY converter and a modified synchronous converter (SR). The converter operates in continuous conduction mode (CCM) and has a non-shock output current, reducing the current stress in the output capacitor and reducing the output...

Implementation of Floating Output Interleaved Input DC-DC Boost Converter

This paper presents the analysin ,design and implementation of a high voltage ratio topology of DC-DC converter. The DC-DC converter has high voltage ratio with reduced input current, output voltage and output current ripple, and also reduces the voltage and current rating of power electronics components and compared with conventional boost converter. The voltage stress on the switches are  red...

Bidirectional Buck-boost Converter with Variable Output Voltage

An increasing number of manufacturing processes rely on ultra-high speed and accuracy machines. Piezoceramic actuators are being utilized as parts of such machines. So far, only linear and switched-capacitor power supplies have been used for driving piezoceramic actuators in such applications. This paper proposes a switch-mode power supply to reduce cost and increase system efficiency. In the p...

A New Transformerless Buck-Boost Converter With Positive Output Voltage

A new transformerless buck–boost converterwith simple structure is proposed in this study. Comparedwith the traditional buck–boost converter, the proposedbuck–boost converter’s voltage gain is squared times of theformer’s and its output voltage polarity is positive. Theseadvantages enable it to work in a wider range of positiveoutput. The two power switches of the proposed buck–boost converter ...
