20kV High-Voltage Supply Design
Budget: ₹1,500 – ₹12,500 INR
I need a complete 20 kV DC power-supply design that can serve rigorous scientific-research setups. The final design has to be electrically safe, mechanically manufacturable, and thoroughly documented so it can move straight to prototype fabrication without re-work.
Scope
• Schematic: full-detail circuit with all protection, monitoring, soft-start, and interlock sections appropriate for 20 kV operation.
• PCB layout: ready-for-fabrication files (Gerber, drill, pick-and-place) that respect high-voltage creepage/clearance and minimise corona.
• Bill of materials: production-available parts with distributor links, voltages, and derating margins called out.
• Supporting files: SPICE or SIMetrix/LTspice simulations that demonstrate expected regulation, ripple, and thermal behaviour; 3-D board files if you work in Altium or KiCad.
Key considerations
– The supply will drive laboratory instruments, so output stability, low ripple, and repeatable calibration are more important than absolute cost.
– Safety is non-negotiable; I will audit your layout for IEC-61010 style spacing, insulation, and bleeder paths.
– If you have proven techniques for modular multiplier stacks, resonance control, or smart feedback using opto-isolated error amplifiers, please apply them.
Deliverables are accepted once the schematic passes a design-for-safety review, the PCB clears a 3-D creepage check, simulations confirm <1 % ripple at full load, and BOM parts show ≥12 months supply continuity.
Please attach a brief note on a previous ≥10 kV project so I can gauge fit.
