What is the difference between half module power supply and full module power supply?

The difference between half-module power supply and full-module power supply lies in the degree of modularity and design complexity of the power supply. Detailed introduction: 1. Semi-modular power supply means that only part of the circuit boards in the power supply design are modularly designed, and other parts are directly welded to the motherboard. Full-module power supply means that all circuit boards in the power supply design are It is modularly designed; 2. Half-module power supply is simpler than full-module power supply. Half-module power supply only needs to design and test the main module of the power conversion circuit, and other auxiliary circuits are directly integrated on the motherboard. Full-module power supplies are more complex in design and so on.

Half-module power supply and full-module power supply are two common power supply design technologies. The main difference between them is the degree of modularity and design complexity of the power supply.

Semi-modular power supply means that only part of the circuit board in the power supply design is modularly designed, while other parts are directly welded to the motherboard. Generally speaking, the modular part of a semi-modular power supply includes the main power conversion circuit, such as switching power supply module, rectifier circuit module and voltage stabilizing circuit module. These modules can be designed, tested and replaced individually, which facilitates power supply maintenance and upgrades. Other auxiliary circuits, such as filter circuits, protection circuits, etc., are directly integrated on the motherboard.

Fully modular power supply means that all circuit boards in the power supply design are modularly designed, including power conversion circuits, filter circuits, protection circuits, etc. Full-module power supplies have a higher degree of modularity, and each functional module can be designed, tested and replaced independently, making the maintenance and upgrade of the power supply more convenient.

From the perspective of power supply design, half-module power supplies are simpler than full-module power supplies. Because the half-module power supply only needs to design and test the main module of the power conversion circuit, while other auxiliary circuits are directly integrated on the motherboard. As a result, the design and manufacturing costs of semi-modular power supplies are relatively low and easier to implement.

However, the design of a full-module power supply is more complex because all circuit boards need to be independently designed and tested. However, the fully modular power supply has a higher degree of modularity, making the maintenance and upgrade of the power supply more convenient. When a certain functional module needs to be replaced, only the corresponding module needs to be replaced without replacing the entire power supply. In this way, the reliability of the full-module power supply is higher and it is easier to customize the design.

In practical applications, the choice of using a half-module power supply or a full-module power supply must be decided according to specific needs. If you have higher requirements on cost and design simplicity, you can choose a half-module power supply. If you have high requirements on reliability and maintainability, or if you need customized design, you can choose a full-module power supply. Of course, this also depends on the application scenario and budget constraints.

To sum up, the difference between a semi-modular power supply and a full-module power supply mainly lies in the modularity and design complexity of the power supply design. Half-module power supplies are relatively simple and low-cost, and are suitable for applications with higher cost requirements; full-module power supplies are more complex, but have higher modularity, better reliability and maintenance, and are suitable for applications with higher reliability and customization requirements. High application.
