This paper deals with a comparative analysis of various converter topologies for Power Factor Correction (PFC) in switched reluctance motor drives. Hence a power factor corrected converter required for obtaining the improved PQ at the AC mains for an inverter fed SRM drive has been analyzed. The SRM when fed by a DBR with a high value of DC-link capacitor results in highly distorted supply curr...

Nowadays there are several grid connected converter in the grid system. These grid connected converters are generally the converters of renewable energy sources, industrial four quadrant drives and other converters with DC link. These converters are connected to the grid through a three phase bridge. The standards prescribe the maximal harmonic emission which could be easily limited with high s...

With an increasing need for higher data rates, both wireless applications and data links are demanding higher speed analog-todigital converters (ADC) with medium resolution. In particular, this work will investigate ADC’s with sampling rate up to 10 Gs/s with 6-8 bits of resolution. Time-interleaved converters achieve their high sampling rate by placing several converters in parallel. Each indi...

Four new topologies of active input current shapers (AICSs) for converters with symmetrically driven transformers (such as half-bridge, full-bridge and push-pull) have recently been proposed. This paper analyzes the extension of the use of these new AICSs topologies to converters with asymmetrically driven transformers. Using some of these topologies, the size of AICS inductors can be reduced a...

In this paper, a new topology is proposed for three-phase to single-phase matrix converters, where more voltage levels are produced in the output in comparison with the conventional topologies. In addition, a new control method based on minimum error between the generated and the desired output voltages is proposed for three-phase to single-phase matrix converters. In the proposed control metho...

Recently digital signal processing has become very popular in video signal processing systems. Analog-toDigital (A/D) converters in this field, namely, video A/D converters, are also popular and have been integrated into mixed-signal system LSIs. Both power consumption and power supply voltage of video A/D converters have been decreasing drastically in recent years [1], [2]. One of the applicat...

High-power converters based on elementary switching cells are more and more used in the industry of power electronics owing to various advantages such as lower voltage stress and reduced power loss. However, the complexity of controlling such converters is a major challenge that the power manufacturing industry has to face with. The synthesis of industrial switching controllers relies today on ...

We discuss a method for increasing the effective sampling rate of binary A/D converters using an architecture that is inspired by biological neural networks. As in biological systems, many relatively simple components can act in concert without a predetermined progression of states or even a timing signal (clock). The charge-fire cycles of individual A/D converters are coordinated using feedbac...

The duality principle is applied to derive new single-stage power-factor-correction (PFC) voltage regulators. This paper begins with an application of duality transformation to conventional discontinuousconduction-mode buck, buck-boost and boost converters. The resulting dual converters operate in the discontinuous capacitor voltage mode. These new converters provide the same PFC property, but ...

This paper presents two prototypes of low power low voltage current mode 9 bit pipelined a/d converters. The first and the second converters are configured of 1.5 bit and 2.5 bit stages, respectively. The a/d converter structures are composed of current mode building blocks and final comparator block which converts the analog current signal into digital voltage signal. All building blocks have ...
