What are the functions of DC-DC switching power supply?
Switching power supply is a kind of electronic equipment that converts alternating current into direct current and is widely used in electronic equipment laboratories, communication equipment, industrial automation and medical equipment and other fields. By providing a stable power supply, the high power DC regulated power supply helps these equipments to operate normally and improve their performance and reliability. Here are some of its functions.
1. Voltage conversion：
Converting one DC voltage to another can ensure that the power supply needs of different electronic devices are met. It can switch between supplying power to high-voltage devices and supplying power to low-voltage devices. For example, the low voltage to the high voltage, or turn the high voltage to the low voltage.
2. Voltage stabilization：
Output a stable DC voltage that is not affected by the input voltage. Although its input voltage is unstable, it will still output a stable voltage to ensure the normal operation of the equipment.
3. Reduce the volume：
If the switching frequency is increased, the external inductors and capacitors will be smaller and will be smaller. Therefore, the external size including the installation area and height will also be smaller, helping to save space.
4. Increase of efficiency：
Compared with traditional linear power supplies, DC-DC switching power supplies have higher conversion efficiency, reduced energy loss, and lower heat generation. In large-scale power usage, the conversion rate can reach up to 98%, which can significantly save energy.
5. Defencive function：
Because the switching power supply will be affected by various electrical and environmental effects in the working process, a series of protection measures such as overload protection, overheat protection, and overvoltage protection are needed to ensure its safe and reliable operation.
In summary, DC-DC switching power supply makes it widely used in electronic equipment laboratory, communication equipment, industrial automation, medical equipment and other fields. And as technology continues to grow, it becomes more and more important.
