How to choose between series and push-pull switching power supplies?

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.05.07
In the field of power electronics, push-pull switching power supplies and series switching power supplies have their own unique application scenarios. In practical applications, it is crucial to choose the appropriate type of switching power supply correctly.

Factors to consider for push-pull switching power supplies:

High power demand: Push-pull switching power supplies can exhibit better performance when the output power is high, and can meet the power supply needs of high-power equipment.

Efficiency requirement: It has high efficiency, especially in heavy load situations, and can effectively reduce energy waste. It is more suitable for long-term operation and high energy consumption equipment.

High frequency applications: In high-frequency working environments, push-pull switching power supplies can better leverage their advantages and ensure stable output.

Factors to consider for series switching power supplies:

Simplicity requirement: Its circuit structure is relatively simple, with low design and implementation difficulty, making it more suitable for applications that require circuit complexity.

Cost limitation: Series switching power supplies typically have lower costs and certain advantages in cost sensitive projects.

Low power applications: In low-power applications, it can meet basic needs while avoiding overly complex designs and high cost investments.

Stability requirements: In some situations where voltage stability is not high, series switching power supplies can provide relatively stable output.

In addition, factors such as application environment, space limitations, and electromagnetic compatibility need to be considered. The final choice should be comprehensively balanced based on specific circumstances to ensure that the switching power supply can meet the requirements of practical applications.

In summary, push-pull switching power supplies and series switching power supplies each have their own characteristics and applicability. We need to make reasonable choices based on specific application requirements to achieve the best performance and benefits.
