The difference between pulse DC power supply and DC power supply

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.03.15
Pulse DC power supply and DC power supply are two very important concepts in the field of electronics, and there are certain differences between them. In the process of use, their characteristics are also different. This article explores the difference between pulse power supply and DC power supply.



1. Output method of current

Firstly, from the perspective of current output mode, pulse power supplies output current in a sudden manner, providing a certain amount of current in a short period of time, which is an intermittent current output mode. DC power supplies, on the other hand, output current in a stable and continuous manner, that is, output a certain current value, usually DC voltage.

2. Stability of output voltage

Secondly, from the perspective of output voltage stability, the output voltage of pulse power supplies is not very stable and is prone to fluctuations due to external interference. Therefore, in some situations where high stability is required for output voltage, the use of pulse power supplies is not suitable. The output voltage stability of DC power supply is good, and it is basically not affected by external factors, so it is very suitable in situations where high stability requirements for output voltage are required.

3. Waveform of output current

At the same time, from the waveform of the output current, the output current of pulse power supplies is generally rectangular or pulse shaped, with extremely high peak current and short current pulses. This is also one of the advantages of pulse power supplies, which can provide a large amount of current in a short time, suitable for use in some high load situations. DC power supplies, on the other hand, output stable current with a flat waveform and no sudden or high current peaks. Therefore, they are suitable for situations where high quality output current is required.

4. Different working principles

The working principles of pulse power supply and DC power supply are also different. The working principle of a pulse power supply is to use capacitors to store electrical energy, and then quickly discharge the capacitors through switching devices to form pulses of current signals. And DC power supply converts AC power supply into DC power supply for output through the conversion of DC power supply.

5. Different usage ranges

Finally, from the perspective of usage scope, pulse power supplies are suitable for some high load, high-power, and high-speed working situations, such as lasers, pulse lasers, high-power LEDs, and so on. DC power supply is suitable for some situations that require stable current and high output quality, such as electronic devices, computers, communication equipment, etc.

In summary, pulse power supplies and DC power supplies are both very important types of power supplies in electronic engineering, and their differences are mainly seen in terms of output mode, voltage stability, current waveform, working principle, and usage scenarios. In practical applications, we need to choose a suitable power supply based on specific usage requirements.
