Introduction to "Energy-Saving Power Supply Technology"

Introduction to "Energy-Saving Power Supply Technology"

Easy noise countermeasures! Achieving high efficiency and energy saving from micro loads to full load range.

This technology is compatible with PWM power supplies such as flyback and forward methods, and it uses a control method based on continuous oscillation, allowing the control frequency to be set for optimal conversion efficiency during standby (light load) and rated (full load) conditions. By aligning the frequency switch with the standby power point, further efficiency improvements during standby can be achieved. This results in high efficiency from standby to full load, enabling a reduction in power consumption. 【Features】 ■ Achieves high efficiency and energy saving from light load to full load ■ Low noise and easy noise countermeasures ■ Smaller ripple voltage compared to intermittent oscillation methods ■ Size reduction of transformers and other components due to improved efficiency ■ Usable for flyback, forward, half-bridge methods, etc. ■ Capable of driving output power up to approximately 1000W *For more details, please refer to the PDF document or feel free to contact us.
