In this paper, we investigate data converters that exploit the possibilities of advanced digital signal processing. After discussing the necessity and prospects of digital signal processing for data converters to comply with next generation system specifications, we demonstrate three examples of digitally enhanced data converters: time-interleaved analog-to-digital converters, all-digital phase...

Three-phase multipulse AC–DC converters (MPC) are developed for improving power quality to reduce harmonics in ac mains and ripples in dc output. This study, based on technical and economic factors, compares different autotransformer-based 30-pulse AC–DC converters. In this paper, the comparison of two topologies of autotransformer-based 30-pulse AC–DC converter has been presented. In topology ...

Ac–ac power conversion, the most popular topologies are indirect ac–ac converters with a dc link matrix converters and direct pulse width modulation (PWM) ac–ac converters. The indirect ac–ac converters and matrix converters can provide variable output voltage and variable frequency. However, for applications, where only voltage regulation is needed, the direct PWM ac–ac converters are used to ...

Various mission-critical applications necessarily require a transformer in switching converters to obtain DC isolation between the converters’ input and output. Since DC-DC converters are the switching devices, these are modeled as hybrid automata. We present hybrid automaton modeling of two main types of transformer isolated DC-DC converters, namely, flyback and forward converters. We have als...

In arithmetic circuits for digital signal processing, radixes other than two are often used to make circuits faster. In such cases, radix converters are necessary. However, in general, radix converters tend to be complex. This paper considers design methods for p-nary to binary converters. First, it considers Look-Up Table (LUT) cascade realizations. Then, it introduces a new design technique c...

This paper examines the determinants and consequences of rural to urban registration (hukou) mobility in contemporary China, focusing on the link between social origins, hukou conversion, and the consequences of conversion. In contrast to massive rural-urban migration, hukou conversion is difficult and rare, but childhood urban residence increases the likelihood of achieving an urban hukou. Com...

This paper presents a comparative evaluation of five topologies of single-phase AC-DC boost converters having power factor correction (PFC). These converter topologies are evaluated on the basis of performance and their salient features are discussed to analyze their applicability. The techniques not only help to develop a deeper understanding of these converters but also to evaluate performanc...

System-level modeling of power electronic converters reproduces only the ideal switching behavior of the semiconductors and is a useful concept for the numerical simulation of power converters, since simulations pres...

The purpose of this application note is to describe the specifications used to quantify the performance of A/D converters and give the reader a better understanding of the significance of those specifications in an application. Although the information presented here is applicable to all A/D converters, specific attention is given to features of the stand-alone and PICmicro A/D converters prod...
