150VA Pure Sine Inverter Design
Budget: ₹37,500 – ₹75,000 INR
I need a robust, 150 VA pure-sine-wave inverter prototype, that runs from a 28 V DC source and cleanly drives EL lighting systems at 40-120V AC (variable), 400 Hz output. The goal is a compact, service-friendly design that delivers flicker-free light without injecting noise back into the DC bus (design will be EMI compliant).
You will take the project from topology selection through to production-ready documentation. High conversion efficiency, low THD, and thermal reliability under continuous operation matter more to me than squeezing every last component cent. Component availability and safety clearances must match standard industrial practices.
Deliverables
• Complete Design Document including Block diagram, schematic with clearly annotated component values, Power calculations and heat dissipation calculations.
• Optimised PCB layout files (Altium, KiCad or similar) plus Gerbers
• Bill of materials with manufacturer part numbers and lifecycle status
• Firmware or control logic for the sine-PWM stage (if a digital controller is used)
• Brief test plan outlining how to verify 150 VA output, sine quality, and protection features
I will handle final prototyping in-house, so please keep the documentation tidy and version-controlled. If you have prior experience with low-noise lighting inverters or EMI-constrained environments, let me know—those insights will be valuable on this build.
