High-Current SMPS Design for LED Wall
Budget: ₹1,500 – ₹12,500 INR
I am looking for an experienced power electronics engineer to design a high-current SMPS for a digital LED video wall application.
## Requirements:
### Input:
* 90–265V AC
* Industrial-grade input protection
### Output:
* 5V @ 60A (300W continuous)
* Low ripple, stable under dynamic load
### Topology:
* Preferred: LLC / Forward / Half-Bridge (not simple flyback)
* Engineer may propose best topology for efficiency and reliability
### Mechanical:
* Compact metal enclosure (industrial SMPS style)
* Airflow / thermal management must be considered
* Size should be as compact as possible
### Electrical Requirements:
* High efficiency (>90%)
* Synchronous rectification preferred
* Proper current sharing / distribution
* Suitable connectors or busbar for 60A output
### Protection:
* OVP (Over Voltage)
* OCP (Over Current)
* SCP (Short Circuit)
* Thermal protection
### Deliverables:
* Full schematic (annotated)
* Transformer design (if applicable)
* PCB layout (high-current optimized)
* Gerber files (ready for manufacturing)
* BOM with exact part numbers
* Thermal and current path considerations
* Assembly drawing
### Additional Requirements:
* Experience in high-power SMPS (>200W mandatory)
* Must understand EMI, thermal, and high-current PCB design
* Should support prototype debugging if needed
## Application:
* Digital LED video wall
* Continuous operation environment
## Goal:
This will be used in a commercial product, so reliability, safety, and manufacturability are critical.
Please share similar past projects and your design approach.
