Technological Breakthrough：reducing standyby power consumption of ac-dc dual-channel module to 0.1w

Technological Breakthrough: Reducing Standby Power Consumption of AC - DC Dual - Channel Modules to 0.1W

Technological Background

In today's era, the Internet of Things (IoT) and smart home devices are becoming increasingly popular. These devices are often in standby mode for long periods, and thus, power management modules' standby power consumption has become a critical concern. Traditional AC - DC dual - channel modules, with relatively high standby power consumption, have struggled to keep up with the market's demand for energy - efficient products.

The push for lower standby power consumption is not only a market demand but also an environmental necessity. As the world focuses more on sustainable development, reducing energy waste in electronic devices has become a global initiative. For instance, international standards and initiatives, such as the “1 W Plan” proposed by the Lawrence Berkeley National Laboratory and adopted by the International Energy Agency (IEA), aim to lower the standby power consumption of electrical products .

In recent years, the technological landscape has witnessed remarkable progress. Through continuous innovation and optimization, engineers and researchers have successfully managed to bring the standby power consumption of AC - DC dual - channel modules down to below 0.1W, which is a significant step forward in energy - efficient power supply technology.

Technological Breakthroughs

Advanced Switching Power Supply Technology

Advanced switching power supply technology is at the forefront of this revolution. This technology allows the power module to operate with high efficiency even under low - load conditions. For example, the quasi - resonant (QR) flyback controller, a modern application of this technology, eliminates the need for optocouplers by using primary - side regulation. It utilizes the magnetic feedback of the transformer's bias winding to form a closed - loop control. Devices like the Texas Instruments UCC28710 controller can reduce switching losses by over 40% by detecting resonant valley voltages and implementing soft - switching techniques .

Optimized Circuit Design

Optimizing the circuit design is another crucial aspect. By carefully analyzing and streamlining the circuit layout, unnecessary power consumption can be minimized. This involves reducing the number of components that consume power in standby mode, as well as improving the overall circuit efficiency. For example, some designs use low - power components and reduce the length of conductive paths to lower resistance and power loss.

Intelligent Control Algorithm

Intelligent control algorithms play a vital role in further reducing standby power consumption. These algorithms can dynamically adjust the output voltage and current according to the real - time load conditions. When the load is low, the algorithm can reduce the output power to a minimum, while still ensuring that the device can quickly resume normal operation when needed.

EBYTE's Technological Advantages

EBYTE has been at the forefront of applying these technological breakthroughs to its AC - DC dual - channel power modules. Products like the AM22 - 12W2412V and AM22 - 24W2412V have achieved standby power consumption below 0.1W, which is a remarkable feat.
