Abstract

Global energy efficiency regulations become increasingly strict, making low-power-consumption power supplies essential for cross-border markets. Adopting low-loss GaN devices and LLC resonant topology,PD GaN fast charger achieves ≥92% full-load efficiency and ＜75mW standby power, fully complying with DoE Level VI and EU ErP standards. This article explains energy-saving principles, actual power consumption parameters and global compliance advantages of PD GaN fast charger for overseas bulk procurement.

1. Core Energy-saving Technical Principles

• PD GaN fast charger uses LLC resonant soft-switching technology to eliminate hard-switching loss, greatly improving power conversion efficiency and reducing heat and invalid energy consumption.

• GaN HEMT devices have ultra-low on-resistance and lower conduction loss than silicon MOSFETs, enabling PD GaN fast charger to save energy under light-load, full-load and standby conditions.

• Intelligent intermittent sleep technology enables PD GaN fast charger to enter low-power sleep mode at no load, strictly controlling standby power within 75mW.

2. Actual Energy Efficiency Compliance Parameters

• PD GaN fast charger achieves ≥92% full-load conversion efficiency, much higher than 85% of traditional silicon chargers, reducing power waste during use.

• Light-load efficiency under 25%, 50% and 75% load meets DoE Level VI standards, solving the problem of high light-load energy consumption of traditional power supplies.

• No-load standby power ＜75mW complies with mandatory standby energy regulations in North America and Europe without customs clearance risks.

3. Overseas Energy Compliance Advantages

• PD GaN fast charger complies with US DoE VI, EU ErP and Australian GEMS standards, adapting to global mainstream markets in one stop.

• Low energy consumption reduces product carbon emissions for overseas brands, conforming to global low-carbon trends and enhancing market competitiveness.

• High efficiency and low heat reduce overall loss, extend the service life of PD GaN fast charger and cut after-sales and operation costs.

Conclusion

Advanced energy-saving architecture and strict efficiency parameters enable PD GaN fast charger to fully comply with global energy regulations, solving the non-compliance and high energy consumption problems of traditional chargers. With energy-saving, high-efficiency and stable advantages, PD GaN fast charger is the optimal cross-border power solution.
