I need a surface-mount power-supply board designed for a consumer-electronics product. The board will run directly from 220–260 V AC and must deliver a regulated 144 V DC at 300–350 mA. Reliability is critical, so the design has to meet a 6 kV surge requirement, include both high- and low-voltage protection, and achieve a high power factor. I already know the exact outer dimensions for the PCB and will forward the drawing as soon as we start; everything has to fit inside that footprint. Apart from those limits, component placement is up to you. I’m leaning toward standard FR-4, but I’m open to alternatives if you see a clear advantage. Please supply the complete schematic, PCB layout, Gerber files, an annotated BOM with part numbers available from major distributo...
I’m developing a compact, aluminium-clad SMD PCB that will live directly on mains, so every detail must be right first time. The board sits on 1 mm aluminium with 25 µm copper, accepts 220-260 VAC and has to deliver a rock-solid 144 VDC at 300-350 mA. Power-factor must stay high thanks to a hybrid DOB topology, while the protection network must survive 6 kV surges and automatically cut in on both high- and low-voltage events. Everything must be RoHS-compliant. Because the board ultimately feeds a power-supply module, thermals and creepage/clearance are just as critical as the electrical design. I’m looking for a clean, production-ready package that lets me hand Gerbers straight to my fabricator and have parts placed with confidence. Deliverables • Complete schema...

I need to reproduce the complete control model from a published paper on grid-connected photovoltaic inverters—specifically the PI + Resonant current controller—and then push the work further by adding an intelligent ANN-based control structure. Everything must be built and run in MATLAB/Simulink so that I can validate the original results first, then make a clear side-by-side comparison between the classical and the new approach. The task starts with an exact replication of the paper: identical parameters, same test grid, and matching waveform plots. Once that baseline is confirmed, you will design, train, and integrate an artificial neural network controller, tune it, and show how it behaves under identical scenarios. I am especially interested in response time, harmonic dis...

Short Summary of the Research This research focuses on designing a high-gain antenna for 5G communication at 36–38 GHz (millimeter-wave). Since 5G at these frequencies suffers from high signal loss, the study aims to improve signal strength using an efficient antenna design. The proposed solution is a compact stacked slot antenna, which provides: Wide bandwidth (34–44 GHz) Stable radiation pattern (consistent signal in all directions) Minimum gain of ~6 dBi (higher in arrays) To improve performance, the antenna is developed in three stages: Single antenna element – basic design and testing 1×2 array – increases gain by ~2–3 dB 1×4 array – further improves gain (~6 dB increase overall) The study proves that increasing the number of antenna ele...
