Generally converter when operated at high frequency results in losses. In this paper a single stage soft switching PFC converter analysis is done. It is developed with a new active snubber cell which provides zero-voltage transition turn ON and zero-current transition turn OFF. This type of converter circuit design does not have additional resonant components. Operating the proposed converter a...

Instead of the A/D converter design, you can also choose to work on a design project of your choice. Consult with the instructors about your project topic. This handout gives an introduction to A/D converter characteristics, testing, and A/D converter types. Characteristics common to all types of A/D converters are discussed in Section 1, together with a test circuit that can be used to verify ...

This paper presents a single-stage ZVT full-bridge AC/DC converter for aerospace applications. The detailed operating principle and design consideration of this soft-switched converter are analyzed and described. The proposed circuit topology and control scheme are proposed to exhibit optimum performances (i.e. high power factor, high efficiency, ring-free and low EMI features). A laboratory pr...

This paper presents an interleaved class E2 dc/dc converter. In the proposed converter, N class E2 dc/dc converters are connected in parallel at the class E rectifier. The proposed converter is suitable to the low-voltage/high-current applications. Since less current flows through the each converter, the amount of the power losses on the parasitic resistances are also reduced. In addition, the ...

A 3-bit, 2-V pipeline analog-to-digital converter has been designed using a modified flash architecture. The developed circuit blocks of the modified flash analog-todigital converter, operating at 135MHz, are a fully differential comparator, a digital-to-analog converter and a sample-and-hold amplifier. The design technique of the N-bit modified flash ADC requires only 2 1) comparators as compa...

In this paper, a multiphase boost converter is proposed to achieve high voltage gain and high power gain. The proposed converter operates in continuous conduction mode (CCM) with soft switching of main and auxiliary devices. The transformer in a conventional converter is replaced by an auxiliary circuit which provides the desired voltage and power levels. The zero voltage switching (ZVS) and ze...

This paper presents comparative performance between Analog and digital controller on DC/DC buck-boost converter four switch. The design of power electronic converter circuit with the use of closed loop scheme needs modeling and then simulating the converter using the modeled equations. This can easily be done with the help of state equations and MATLAB/SIMULINK as a tool for simulation of those...

A CMOS voltage-to-current converter in weak inversion is presented in this Letter. It can operate for low supply voltage and its power consumption is also low. As the input voltage varies from −0.15 V to 0.15 V, the measured maximum linearity error for the proposed voltageto-current converter, is about 3.35%. Its power consumption is only 26 μW under the supply voltage of 2 V. The proposed volt...

This document describes several aspects relating to the design of dc-dc converters operating at frequencies in the VHF range (30-300 MHz). Design considerations are treated in the context of a dc-dc converter operating at a switching frequency of 100 MHz. Gate drive, rectifier and control designs are explored in detail, and experimental measurements of the complete converter are presented that ...

Problem statement: A half-bridge LLC resonant converter with a voltage doubler rectifier has a simple structure and its Zero-Voltage-Switching (ZVS) capability is excellent from zero to full load condition. But conduction loss is more due to high circulating energy thus reducing the system efficiency. Moreover a variable frequency control method makes the control circuits more complicated than ...
