As SOC and complex systems usually include analogue IPs, it becomes more important to test analogue devices efficiently. The reason for this is that analogue testing for high quality requires substantial testing costs although the analogue portion in a whole chip or in a system is usually very small. In the paper, an efficient low-cost built-in self-test (BIST) scheme is developed for testing A...

In this paper, Fuzzy Logic controller is developed for ac/ac Matrix Converter. Furthermore, Total Harmonic Distortion is reduced significantly. Space Vector Algorithm is a method to improve power quality of the converter output. But its quality is limited to 86.7%.We are introduced a Cross coupled DQ axis controller to improve power quality. The Matrix Converter is an attractive topology for Hi...

A novel three-phase AC-DC-AC Sparse Matrix Converter (SMC) having no energy storage elements in the DC link and employing only 15 IGBTs as opposed to 18 IGBTs of a functionally equivalent conventional AC-AC matrix converter (CMC) is proposed. It is shown that the realization effort could be further reduced to only 9 IGBTs (Ultra Sparse Matrix Converter, USMC) in case the phase displacement of t...

In this paper we design a fuzzy adaptive internal model control for the speed varying problem of a PMSM. The PMSM under the vector control model is studied. The designing of the fuzzy adaptive IMC involves three steps. First a standard internal model controller is designed. This model has high input saturation. A modified IMC is designed which reduces the input saturation. The variation of iner...

Testing of analogue circuits and mixed-mode circuits has recently gained much attention in the literature. The subject covers testing of many different classes of circuits such as A/D and D/A converters, PLLs, amplifiers, TV circuits, telecommunication circuits and many others. Analogue testing is carried out in order to ensure that the circuit performs as expected both in functional terms and ...

This paper describes a DC isolated network which is fed with Distributed Generation (DG) from photovoltaic (PV) renewable sources for supplying unbalanced AC loads. The battery energy storage bank has been connected to the DC network via DC/DC converter to control the voltage of the network and optimize the operation of the PV generation units. The PV arrays are connected to the DC network ...

This paper investigates a novel single stage AC–AC power conversion, as an alternative to multistage AC– DC–AC power conversion topology, for interfacing the wind energy conversion system (WECS) to a grid as a distributed load system. A comprehensive dynamic model of proposed AC–AC converter is developed to satisfy all the functions of the converter. A new time switching pattern and a control m...
