@tetianam8

⭐⭐⭐⭐⭐ This is not a generic power-supply job — it’s an industrial DC bus design problem where regulation, inrush handling, and protection all have to be engineered together. A stable 120 VDC source for a high-current 3-phase motor application needs the right front-end topology, bulk energy storage, current limiting, and fault shutdown strategy from the start. I can deliver a clear, build-ready schematic package focused on: • stable 120 VDC output under heavy load • inrush/surge handling for motor startup conditions • over-current, over-voltage, and thermal protection • industrial-rated component selection with proper margins • commissioning/test points and scaling notes for future uprating Deliverables: Complete schematic in PDF + editable format (KiCad / Altium / LTspice) BOM with part numbers, ratings, and sourcing notes Short design note covering topology choice and protection logic Recommended test points for startup and troubleshooting Quick questions: • What is the input source feeding the 120 VDC stage? • Required continuous current and peak/inrush current? • Is this feeding a VFD/inverter stage or a custom motor drive? If you share the load specs, I can turn this into a practical, protection-focused design quickly.

@joaquinc48

✅✅✅ Industrial Power Electronics & DC Supply Design Engineer ✅✅✅ Hi there, I have experience designing high-power DC supplies and industrial power stages, including rectification, protection circuits, and high-current power distribution. My work often focuses on robust power architectures capable of handling heavy inrush currents, thermal stress, and long-term industrial operation. My approach is to design a reliable 120 V DC supply using an appropriate rectifier or SMPS topology with properly rated components, soft-start/inrush control, and layered protections (overcurrent, overvoltage, thermal). I will also define clear test points and a scalable protection strategy for future power upgrades. A few questions: What input power source will feed the system (single-phase or three-phase AC)? What continuous current and peak inrush current should the design support? Do you prefer passive rectification or a regulated DC stage? I am ready to start immediately. Best regards

@taraskkorol

Hello, and thank you for sharing your detailed requirements for the 120 V DC power supply. I would be honored to help you create a gracefully structured, technician-ready schematic that balances high-current capability with robust protection. With your industrial three-phase motor application in mind, I will design a clean, reliable 120 V DC output that stays stable under heavy load, incorporates thoughtful inrush management, and embeds comprehensive safeguards against over-current, over-voltage, and thermal stress. My deliverable will include a complete, clearly annotated circuit diagram in your preferred PDF or CAD format, a precise bill of materials with high‑amperage-rated components, an elegant design note on how each protection layer functions and scales, and marked test points for commissioning and troubleshooting. This approach ensures your technicians can build confidently while leaving room for future motor upgrades. Would you prefer the design optimized around a discrete rectifier stage, a switched‑mode topology, or should I provide a comparison to guide your final selection? Warm regards, Taras
