High-Current SMPS Design for LED Wall

Job ID: 40397921

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.
