    FAQ

    Q1: What is switching power supply's working principles?

    A switching power supply works by rapidly turning electronic switches on and off to convert input AC or DC voltage into high‑frequency pulses, which are then transformed, rectified, and filtered to produce a stable DC output; a feedback circuit continuously adjusts the switching duty cycle to maintain constant output voltage, making it highly efficient, compact, and widely used in electronic devices.

    Q2: What are common applications of switching power supplies?

    Switching power supplies are widely used in computers, laptops, mobile phone chargers, TVs, monitors, industrial equipment, LED lighting, automotive electronics, communication devices, medical instruments, and home appliances because they are efficient, compact, and able to provide stable voltage for various electronic products.
