<span lang="EN-US">This paper proposes a new bidirectional step-up DC-DC converter, namely modified buck-boost converter. The proposed converter was derived from the conventional Output voltage expression of by considering drops across inductors and switching devices. results have shown that with same parameter input LC filter, has lower conduction losses. Moreover, rated filter capacitor...

The main purpose of this paper is to introduce an approach to design a DC-DC boost converter with constant output voltage for grid connected photovoltaic application system. The boost converter is designed to step up a fluctuating solar panel voltage to a higher constant DC voltage. It uses voltage feedback to keep the output voltage constant. To do so, a microcontroller is used as the heart of...

In this paper, H∞ loop-shaping control is applied to improve the performance of a buckboost dc-dc power converter based on pulse-width-modulation (PWM) techniques. Here, classical control techniques (i.e., proportional-integral-derivative (PID) control) and post-modern control techniques (i.e., H∞ control), are used to design the feedback loop of a buck-boost dc-dc power converter. The results ...

This paper presents a high step up DC-DC converter to boost low voltage PV system voltage. The switched capacitor converter can obtain a high voltage gain but the line and load regulation is poor and the output voltage is not regulated. The output regulation of the non isolated switching mode DC-DC converter is excellent but the voltage gain cannot be too high.A combination method of the SC con...

An isolated switched high step up boost DC-DC converter is discussed in this paper. The main objective of this paper is to step up low voltage to very high voltage. This paper mainly initiates at boosting a 30V DC into 240V DC. The discussed converter benefits from the continuous input current. Usually, step-up DC-DC converters are suitable for input whose voltage level is very low. The circuit...

In our paper, a method of using hybrid converter has been implemented. In the existing system, two stage approaches has been used. This two stage approach is both dc –dc converter and dc – ac Converter. This type of converters mentioned above has been used in the earlier stages, but the drawbacks that can be seen is increased cost and complexity. The proposed method mainly uses boost derived hy...
