Signal Processing Power Inverter Design
Budget: $250 – $750 USD
I’m developing a signal-processing module and need a purpose-built power inverter circuit to drive it reliably from a 12 V DC source. The job centres on circuit design; PCB work can follow later once the schematic is locked down.
Here’s what I’m looking for:
• A complete schematic for a high-efficiency DC-to-AC inverter that delivers clean, low-ripple rails suitable for sensitive analogue and mixed-signal stages.
• Component selection with readily available parts and clear justification for each choice.
• SPICE-level simulations (LTspice, PSpice or similar) showing expected efficiency, output wave-form quality and thermal performance under 25 W continuous load.
• A brief design report summarising calculations, key assumptions and any trade-offs made.
Acceptance criteria
• Total harmonic distortion ≤ 3 % at full load.
• Output voltage regulation within ±2 %.
• Thermal rise of power switches < 40 °C above ambient in simulation.
If you have previous inverter or signal-conditioning work to showcase, I’d love to see it. Let’s create a rock-solid foundation for the rest of the system.
