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...

In this paper, non-integer order control is applied to improve the performance of a buck-boost dc-dc power converter with ultracapacitor based on state feedback techniques. The approach is based on stabilization in the Lyapunov's sense for linear rational-order systems. The ultracapacitor can overcome the classical problems of energy losses due to the use of batteries, giving more accuracy, aut...

In this paper, a boost converter with a clamp circuit is proposed for high intensity discharge (HID) lamp application. The clamp circuit provides zero voltage turn on for both main and clamp switches. Compared to conventional boost converters, the proposed converter has the following advantages: (i) high voltage gain without suffering from extreme duty ratio, (ii) low stress on the switches and...

As generally acknowledged, the high-gain DC-DC converter is widely used in the sustainable energy system as the front-stage of the DC-AC converter. Therefore, it is indispensable for low voltage to be boosted to high voltage. In general, the boost converter or the buck-boost converter is widely used in such applications. However, it is not easy for such converters to achieve high voltage ratio....

Received Jan 2, 2014 Revised Mar 12, 2014 Accepted Mar 25, 2014 This paper proposes the single-switch bridgeless boost power factor correction (PFC) converter to achieve high efficiency in low cost. The proposed converter utilizes only one active switching device forPFC operation as well as expecting higher efficiency than typical boost PFC converters. On the other hand, the implementation cost...

The paper focuses on a DC/DC converter that is used to adapt a varying output voltage from a solar panel to demands of an electrolyzer unit or battery charging purposes.
