This paper presents a novel grid-connected photovoltaic Microinverter topology and its control implementation. A very significant contribution is to propose an innovative conversion structure with the aim of achieving high efficiency, easy control, high reliability and low design cost. In a first part of this contribution, we describe the proposed configuration topology. In a second part, we present...
Ever increasing energy consumption and pollution caused by burning of fossil fuels to meet our energy requirements have led researchers to focus on alternate forms of energy which are clean. Solar, wind and fuel cells are the areas in which research is going on with fast pace. Solar and wind have their drawbacks since electricity is generated only when sun shines or wind blows while fuel cells can...
KY Boost Converter, a recent invention in the field of non-isolated DC-DC boost converter is identified for minimum voltage ripple. In this article a Fuzzy controller is designed and implemented to minimize the output voltage ripple of the KY boost converter output. The Fuzzy controller is designed in MATLAB/Simulink model and the digitally simulated results show a reduction in output ripple from...
The output voltage of DC-DC converter contains the ripple and it substantially affects the frequency response although the ripple is usually neglected in the control circuit as PWM control. The authors already have clarified that the effect of the ripple is not ignorable for the frequency response and it causes the unusual characteristics. In this paper, we analyze the effect of the ripple in consideration...
This paper describes the design of a fast response zero-voltage-transition (ZVT) pulse-width modulation (PWM) boost converter. The techniques employed in the design include a combination of a PWM variable gain control and zero-voltage switching (ZVS), to improve the switching speed and efficiency of the converter for high frequency operation. A prototype was built to verify the design and to compare...
