Abstract

As an external power supply, energy efficiency of a power adapter is a mandatory market-access requirement. The power adapter must meet DOE Level VI and EU ErP efficiency standards. This power adapter covers full-load efficiency, standby power and light-load efficiency parameters, helping companies assess energy performance, meet global rules and lower long-term operating energy.

1. Energy Regulation Background

The power adapter must meet US DOE Level VI and EU ErP directives. Non-compliant power adapter products will be banned from sale. Energy design of the power adapter runs through circuit and component selection.

2. Full-Load Efficiency Parameters

Full-load efficiency of the power adapter must reach the minimum limit of DOE VI. Efficiency limits of the power adapter differ by power range. High-efficiency design of the power adapter lowers operating loss and heat.

3. Standby Power Parameters

No-load standby power of the power adapter must be below 0.075W (DOE VI limit). Standby power of the power adapter is a key market surveillance item. The power adapter uses low-quiescent-current control chips to cut standby loss.

4. Light-Load Efficiency Optimization

The power adapter must meet efficiency limits at 25%, 50% and 75% load points. Light-load efficiency of the power adapter is optimized with burst mode. Multi-load compliance guarantees overall energy conformance.

5. Value of Energy Compliance

Energy compliance of the power adapter is prerequisite for EU and US customs clearance. High-efficiency power adapter appeals to green procurement customers. Energy-saving design lowers long-term operating cost.

Conclusion

High efficiency and low standby of the power adapter meet global energy regulations. For power adapter efficiency test data, contact Simsukian for reports and samples.
