Grid-tied photovoltaic (PV) installations with distributed maximum power point tracking (DMPPT) architectures include a dc-dc module integrated converter (MIC) for managing each PV panel, isolating it from the others, reducing mismatching effect and maximizing harvested power. In this article, autotransformer forward type-Zeta resonant reset (AFZ) is proposed as DMPPT architecture's MIC candida...

The development of digital IIR (Infinite Impulse Response) filter is done on VIRTEX-6 FPGA using VHDL (Very High Speed Integrated Circuit Hardware Description Language) in XILINX Integrated Software Environment. IIR filter is analytically simulated by simulink environment in MATLAB. The digital data output of A/D converter is sent through IIR module in FPGA. Testing and debugging IIR module is ...

In our paper, a method of using hybrid converter has been implemented. In the existing system, two stage approaches has been used. This two stage approach is both dc –dc converter and dc – ac Converter. This type of converters mentioned above has been used in the earlier stages, but the drawbacks that can be seen is increased cost and complexity. The proposed method mainly uses boost derived hy...

3.3kV high speed IGBT module was developed. Optimized lifetime control realized drastically decreasing of both of turn off loss and recovery loss. This high speed characteristic is suitable for bi-directional and medium frequency application such as resonant DC/DC converter. IGBT switching and diode reverse recovery behaviour at resonant DC/DC converter modelled circuit were demonstrated. Obvio...

In this paper, we report a miniaturized low-power wireless remote environmental monitoring system. This system has been developed for on-site monitoring of water pollution by heavy-metal ions. The system is composed of three parts: an electrochemical sensor module using microfabricated electrodes for detecting heavy-metal contamination in sample water; a custom potentiostat module including rea...

This experimental study deals with the investigation of chaos during the regulation of output voltage of solar photovoltaic module. The Cuk converter is used as an interface between solar PV module and load, since the Cuk converter is the good choice for the maximum power point tracking (MPPT) circuits. The input voltage of the converter is controlled in order to regulate the operating point of...

In this paper, we present design, implementation, and measurement of a three-dimensional (3-D)-deployed RF front-end system-on-package (SOP) in a standard multi-layer low temperature co-fired ceramic (LTCC) technology. A compact 14 GHz GaAs MESFET-based transmitter module integrated with an embedded band pass filter was built on LTCC 951AT tapes. The up-converter MMIC integrated with a voltage ...
