Full custom support case study for AC/DC Power Adapter for industrial equipment | Optimization through power supply design based on requirements specifications
A case study of full custom support for AC/DC Power Adapter for industrial equipment. We introduce an example of custom power supply development optimized from the design stage to meet required specifications that cannot be handled by existing Products.
目次
What Is Full Custom Support
Full custom support refers to custom power supply development designed from scratch based on required specifications, including circuit configuration, component selection, and specification conditions.
When existing Products or semi-custom solutions cannot meet requirements, we develop a power supply optimized for the specific equipment application.
Background of the Consultation | Why Semi-Custom Was Not Feasible
In this case, we initially considered a semi-custom approach, but as we clarified the specifications, the following challenges became apparent.
- The required noise immunity far exceeded the scope of existing designs
- Safety standards for the target country significantly impacted the design from the initial stage
- Interference with the equipment structure made it difficult to use existing configurations
For these reasons, we determined that full custom support was necessary.
Key Items Confirmed During the Hearing Stage
In full custom projects, the initial hearing process is extremely important. In this case, we focused on the following.
- Operating environment (indoor/outdoor, temperature and humidity conditions)
- Target countries and required safety standards
- Equipment lifespan and MTBF requirements
- Plans for future model development
Scope of Support | Design Optimization Based on Required Specifications
Based on the above hearing details, we conducted the following design considerations.
- Circuit configuration design with noise countermeasures
- Component selection suited to the operating environment
- Optimization of cable and connection specifications
- Design in compliance with safety standard requirements
As a result, we achieved a power supply design optimized for the equipment specifications.
Key Points We Emphasize in Full Custom Support
UNIFIVE places emphasis on the following in full custom projects.
- Design with mass production in mind, not just prototyping
- Ensuring component procurement stability and consistent quality
- Flexibility for future specification changes
Differences from Semi-Custom
| Item | Semi-Custom | Full Custom |
|---|---|---|
| Design Base | Existing design | New design |
| Scope of Support | Partial specification adjustments | Overall optimization |
| Development Period | Short | Medium to long |
| Initial Cost | Low | High |
Cases Suitable for Full Custom Support
- Standard or semi-custom products cannot meet the required specifications
- Safety standards significantly impact the design
- A dedicated power supply for specific equipment is required
UNIFIVE proposes the most suitable approach while avoiding overdesign, whether semi-custom or full custom. Please feel free to consult with us starting from the specification planning stage.
