Core Distinctions Between High-Frequency Switching Power Supplies and AC-Based Switching Power Supplies
The high-frequency switching power supply is designed to charge the battery while supplying power to the DC load. If they are combined together, it will be a DC power supply screen. The DC power supply panel can provide power for distribution protection, signal, monitoring, emergency lighting, and circuit breaker operation. Today, we mainly understand the specific differences between high-frequency switching power supplies and AC switching power supplies
1. The main difference between high-frequency switching DC power supply and AC switching power supply lies in whether there is a difference in current direction. The so-called alternating current lies in the alternating circulation of current and its direction changing alternately. Ring transformer is an AC switching power supply, and the output of the transformer is not divided into positive and negative poles, which can be connected freely.
2. Direct current refers to a current whose direction does not change over time but whose amplitude can vary. The determined output current is also a constant current source, such as a switching power supply. Direct current is represented by direct current or a straight line, such as DC12V-24V. High frequency switch DC power supply is divided into positive and negative poles. If the connection is reversed, it will burn out the power supply.
In fact, a toroidal transformer can also provide direct current and only requires one component - a rectifier bridge - to meet the requirements. Sometimes multiple filtering capacitors are added to make the power supply more stable and undisturbed.
3. Communication can be converted into direct current. Usually, computers, mobile phones, and other devices are plugged directly into AC power sockets, while our phones and computers use DC power. Therefore, there are doubts because the power grid uses alternating current to generate and transmit electricity.
4. Communication fluctuates sinusoidally on the timeline, increasing from 0 to the upper limit, then gradually decreasing from the upper limit to 0, then gradually decreasing from 0 to the negative upper limit, and then returning to 0. Our electronic components such as phones and computers can recognize high and low potentials. Due to its sinusoidal fluctuations, alternating current generates high and low potentials, which contradicts the logical evaluation of electronic components.
