1. How efficient is an AC/DC converter?
The efficiency of AC/DC converters is usually between 70%-95%, depending on the design, topology and load conditions of the converter. Switching power supply topologies are generally more efficient.
-
2. What factors should be considered when selecting an AC/DC converter?
Factors such as input voltage range, output voltage and current requirements, power efficiency, packaging, temperature range, reliability and safety certification need to be considered when selecting.
-
3. How to improve the efficiency of AC/DC converters?
Choose a more efficient switching topology (such as resonant or quasi-resonant topology), use more efficient semiconductor devices (such as GaN or SiC transistors), and optimize circuit design to reduce switching losses and heat losses.
-
4. Are offline switching power supplies suitable for high power applications?
Offline switching power supplies can be used for high power applications, but proper heat dissipation and power management solutions must be designed to ensure conversion efficiency and stability. Choosing a suitable topology such as LLC resonant converter can also help achieve high power output.
