applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...
In the paper an adaptive filter of witch characteristics track changes of the observations conditions in real-time with use of the enhanced TMS320C6701 Evaluation Module board is described. This filter can be used to cancel narrow bandwidth interferences with unknown power spectral density from a received radar signal. This real-time process requires fast A/D converter. We achieved this by usin...
a new intelligent photovoltaic (PV) panel structure to extract the maximum power in mismatch irradiance is proposed. In conventional structures, difference of irradiance between series panels can cause the deviation of maximum power point. In this condition tracking MPP becomes difficult and reduces efficiency. Improvements in power electronics and its effects in PV industrial technology, devel...
This paper presents a buck-boost converter-based bipolar pulse generator, which is able to generate bipolar exponential pulses across a resistive load. The concept of the proposed approach depends on operating the involved buck-boost converters in discontinuous current conduction mode with high-voltage gain and enhanced efficiency. A full design of the pulse generator and its passive components...

In this paper, an efficient testing system for measuring a PV module’s I-V curve is proposed. The proposed system is based on a controlled DC-DC boost converter. The advantage of using a DC-DC converter is that this converter is typically used in PV systems to track the maximum power point and to control the charging of the battery. Consequently, this device is utilized for I-V curve extraction...
Here an improved three-level integrated ac–dc converter is presented. This converter improving or boosting power factor correction. And also this converter topology is advanced than previous ac-dc converters mainly the converter is operating with two independent controllers. An input controller is used to power factor correction and it regulates the dc bus, and the output controller is used to ...
In this paper, Performance of three-level integrated ac–dc converter with Hysteresis Current Control Technique is presented. The proposed converter combines with the operation of the boost power factor correction and the three-level dc–dc converter. By the implementation of Hysteresis Current controller, the switching sequence is under controlled condition and the output voltage of the proposed...
In this paper, a new step-up/step-down AC-AC converter is designed by switched capacitor (SC) techniques. The main features of the proposed SC AC-AC converter are the symmetrical converter topology and the absence of magnetic elements. Owing to the symmetrical converter topology, the number of capacitors in the proposed AC-AC converter is fewer than that in the conventional SC AC-AC converter. ...
