The following discussion examines an overlooked option for many existing A/D converter applications: the A/D conversion is sometimes better implemented with a discrete comparator and D/A converter. This substitution generally entails a different measurement approach, but the advantages can include lower cost, higher speed, more flexibility, and lower power consumption. Current trends, though, a...

In this study, a robust controller for voltage regulation of the POESLL converter worked in continuous conduction mode is presented. POESLL converter is a DC/DC converter with a high voltage gain. DC/DC converters are used in telecommunication systems, power sources and industrial applications. Owing to the switching operation, the structure of the POESLL converter is highly non-linear. In addi...

Abstract: This paper proposed a new type of converter called Single Phase Switched Inductor Z-source Matrix Converter (SLMC). It is an ac-to-ac converter with diode bridge bidirectional switch cell. The limitations of existing matrix converter like voltage regulation and quality output issues are overcome in the proposed SLMC by adding the switched inductance. The simulation is performed for di...

Arterial load is composed of resistive and various pulsatile components, but their relative contributions to left ventricular (LV) remodeling in the general population are unknown. We studied 4145 participants enrolled in the Multi-Ethnic Study of Atherosclerosis, who underwent cardiac MRI and radial arterial tonometry. We computed systemic vascular resistance (SVR=mean arterial pressure/cardia...

This paper presents a simple circuit technique based on commercially available devices for measuring the amplitude of transient signals. The proposed technique produces digital output proportion to the amplitude of sinusoidal analog input signal without low-pass filter. The realization method employs a peak detector, a comparator, an analog-to-digital converter, and a microcontroller. In additi...

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...

This paper consist of two sections: control and stabilizing approach for chaotic behaviour of converter is introduced in first section of this paper for the removal of harmonic caused by the chaotic behaviour in current converter. For this work, a Time- Delayed Feedback Controller (TDFC) control method for stability chaotic behaviour of buck converter for switching courses in current control mo...

The integration of text-to-speech (TTS) synthesis and animation of synthetic faces allows new applications like visual human computer interfaces using agents or avatars. The TTS informs the talking head when phonemes are spoken. The appropriate mouth shapes are animated and rendered while the TTS produces the sound. We call this integrated system of TTS and animation a Visual TTS (VTTS). This p...
