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 ...

Analysis of New Transformerless dc-dc Converter With High Voltage Gain

In some industries applications such as fuel cells, we must use a high voltage gain dc-dc converters for increasing voltage, but, the conventional converters cannot provide the high voltage gain with increasing duty cycle and the converters efficiency is limited by the equivalent series resistances. For this reason, in this paper, a single switch transformerless high step-up dc-dc converter wit...

A Buck Converter Based On PID Controller for Voltage Step-Down Application

This paper present a pulse width modulation non-isolated buck converter using PID controller. The buck converter constituted by one Gto, one inductor, one capacitor, one diode and one load resistor. In this the buck converter connected to the PID controller, PID controller calculate an error value as the difference between a measured process variable and a desired set point. The proportional P ...

A Novel Converter Topology for High Step-Down Conversion Ratio DC-DC Converter with Low Voltage Switch Stress

In this paper, a novel converter topology for interleaved high step-down conversion ratio dc–dc converter with low switch voltage stress is proposed. In the proposed converter, two input capacitors are series-charged by the input voltage source and parallel discharged by a new twophase interleaved buck converter topology without adopting an extreme short duty cycle for delivering a much higher ...
