500VA Inverter Circuit Design Consultant
Budget: ₹1,500 – ₹12,500 INR
I’m building a 500 VA Home Inverter and need an experienced engineer / consultant to refine the entire circuit design. I already have a rough block diagram and basic requirements; what I’m missing is a rock-solid schematic that can be taken straight into PCB layout.
Here’s what I’m looking for:
• Validate and optimise the topology (full-bridge or push-pull—open to your recommendation) for a pure-sine output.
• Size and select magnetics, switching devices and gate-drive arrangements so the design runs cool and efficiently at 500 VA.
• Provide complete schematics with all component values, protection circuitry and control logic.
• Run SPICE simulations (LTspice, PSpice or similar) to demonstrate THD, efficiency and thermal margins under full and partial load.
• Brief notes on EMI/EMC considerations and how the design can scale if I later step up toward 1 kW.
Deliverables I need from you:
1. Finalised circuit schematic in PDF and native CAD format (KiCad, Altium or OrCAD).
2. Simulation files with clearly labelled test points and plots.
3. A concise design report summarising key calculations, assumptions and test results.
I can share my preliminary diagram and performance targets once we start. If you’ve taken a low-power inverter from concept to production before, I’d love to see an example of your work and hear how you’d approach this project.
