  AC and DC power supplies: What’s the difference?

  In modern power systems and electronic devices, AC and DC power supplies are the two most common types of power supplies. They each have unique characteristics and application scenarios, and are of great importance to our lives and industrial production. So what are the differences between AC and DC power supplies? First of all, by definition, an AC power supply refers to a power supply whose direction and magnitude change over time. In an AC power supply, the direction of the current changes periodically, meaning the positive and negative charges move alternately. Because of this periodic change, the voltage and current of an AC power supply are usually represented by a sine wave, and the frequency is usually 50Hz or...
