✅Okay, I got what you want exactly. I am a senior electrical engineer with over 10 years of experience, providing power electronics design, transformer-rectifier systems, AC/DC conversion, and lighting power solutions. In my opinion, this project needs a robust, conservative design approach to ensure stable 74VDC output under load while maintaining efficiency and thermal safety. I would focus on proper transformer sizing, rectification topology, filtering, and protection to make the unit reliable for long-term indoor operation. This project is very similar to my previous works. I have designed transformer-rectifier units ranging from 500VA to 2kVA, including a 120VAC to 60–80VDC power supply for industrial LED lighting where I calculated secondary winding specs, selected bridge rectifiers rated above 25A, and designed LC filtering to keep ripple below 3%. I have also specified insulation class, thermal margins, and inrush protection for indoor power equipment. ✅ So, I will divide your project like following: ⚡ Requirements confirmation and load analysis ⚡ Transformer design (primary/secondary, VA margin, insulation class) ⚡ Rectifier, filtering, and protection circuit design ⚡ Detailed schematic, BOM, and component specifications Via private chatting or meeting, I will provide the creative idea and good tech solution for your project and i want to discuss about the budget and timeline in detail.
