In this paper a single-inductor dual-output (SIDO) buck-boost PFC converter operating in critical conduction mode (CRM) is proposed. By multiplexing a single inductor, each output of SIDO buck-boost converter can be regulated independently. Compared with conventional two-stage multiple output converter, SIDO buck-boost PFC converter benefits from significant overall cost saving, small size and ...

In this paper, a two-stage AC/DC converter is presented for a low-profile laptop adaptor. The system consists of a boost power factor pre-regulator and LLC resonant converter. The pre-regulator features high PF and high-efficiency, while secondary LLC converter features zero voltage switching (ZVS). The transformer in LLC converter is splited in two to reduce current stress and converter height...

DC DC converters are widely used in a variety of applications. It is mostly used in tracking maximum power point of PV array. The tapped inductor is a feasible method to extend the voltage conversion ratio. In this paper, the effect of tapped inductor in a boost converter is discussed. This paper provides a detailed design and analysis of a tapped inductor boost converter. The performance of th...

A zero voltage switching (ZVS) dc–dc converter with high voltage gain is proposed. It consists of a ZVS boost switch cell converter stage and a ZVS half-bridge converter stage with resonant converter and all these stages are merged into a single stage. The ZVS boost converter stage provides a continuous input current and ZVS operation of the power switches. The ZVS halfbridge converter stage pr...

Many grid connected PV installations consist of a single series string of PV modules and a single DCAC inverter. This efficiency of this topology can be enhanced with additional low power, low cost per panel converter modules. Most current flows directly in the series string which ensures high efficiency. However parallel Cúk or buck-boost DC-DC converters connected across each adjacent pair of...

For federally managed fisheries in the USA, National Standard 1 requires that an acceptable biological catch be set for all fisheries and that this catch avoid overfishing. Achieving this goal for data-poor stocks, for which stock assessments are not possible, is particularly challenging. A number of harvest control rules have very recently been developed to set sustainable catches in data-poor...

The KY Converter, Which is a step up converter, The name given to this converter is first letter of the authors, K.I. Hwu, Y. T. Yau. This converter always operate in CCM, and the output current is non-pulsating, and low output voltage ripple and higher voltage boosting capability. In this paper, different modes of KY Converters are studied. The simulation is carried out to study the perfomance...

This paper proposes a high voltage ratio and low ripple interleaved boost DC-DC converter, which can be used to reduce the output voltage ripple. This converter transfers the low DC voltage of fuel cell to high DC voltage in DC link. The structure of the converter is parallel with two voltage-doublers boost converters by interleaving their output voltages to reduce the voltage ripple ratio. Bes...

In this paper, a new reverse converter for the moduli set {2n, 2n–1, 2n–1–1} is presented. We improved a previously introduced conversion algorithm for deriving an efficient hardware design for reverse converter. Hardware architecture of the proposed converter is based on carry-save adders and regular binary adders, without the requirement for modular adders. The presented design is faster than...

this paper presents a detailed small-signal and transient analysis of a full bridge pwm dc-dc converter designed for high voltage, high power applications using an average model. the derived model is implemented in a typical system and used to produce the small-signal and transient characteristics of the converter. results obtained in the analysis of the high voltage and high power design examp...
