Design 150W Sine Inverter
Budget: ₹12,500 – ₹37,500 INR
I need a compact, 150 W Pure-sine-wave 400 Hz inverter purpose-built for an industrial environment. It will run from a 24 V DC battery rail and must deliver a clean, low-distortion AC output suitable for factory instrumentation, control boards, and the occasional small motor or pump.
Here’s what I’m looking for:
• A complete, production-ready design package: schematic, PCB layout, transformer or inductor specs, and a clearly itemised BOM with readily available components.
• The 24V DC input is to be converted into pure sine wave out put using analog SPWM techniques.
• Built-in protections—over-current, short-circuit, reverse polarity, thermal, and under/over-voltage—because this unit will sit in a harsh, always-on setting.
• Efficiency above 90 % at half load and a total harmonic distortion below 3 %.
• A brief test report that proves continuous 150 W output, stable operation from –40 °C to 70 °C.
• Optional EMI filter recommendations.
Skills and Experience:
- Experience in designing and building sinewave PWM inverter circuits.
- Knowledge of power electronics and circuit design.
- Ability to select appropriate components for the project.
- Attention to detail and ability to ensure the circuit meets the required specifications.
If you have the necessary skills and experience, and are interested in working on this project, please submit your proposal.
