1. How does an AC/DC converter work?
An AC/DC converter converts AC to DC through a rectifier circuit, and after filtering and voltage stabilization, it finally provides a stable DC output. Offline switching power supplies also use switching regulation technology to improve efficiency.
-
2. What are some common applications of PMIC AC/DC converters?
PMIC AC/DC converters are widely used in scenarios that require AC power to DC, such as chargers, adapters, LED driver power supplies, industrial control equipment, smart home devices, and battery management systems.
-
3. 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.
-
4. How important is power factor correction (PFC) for AC/DC converters?
Power factor correction (PFC) is very important for meeting energy regulations and improving power efficiency, especially in high-power applications. PFC circuits can reduce the harmonic interference of equipment to the power grid.
