1. Concept of bare board and complete power supply

The bare board of switch mode power supply refers to a power board without a shell or packaging, which is an important component of the power supply technology research and development process. A complete power supply is a complete power product that encapsulates, casings, interfaces, filters, and other components of this bare board, which can be directly used for the power supply of various electronic devices.

2. Differences in price and volume

The bare board of the switch power supply is more affordable compared to a complete power supply due to the lack of accessories such as a shell or interface. Meanwhile, bare boards do not require an outer shell to secure components, and their volume is relatively smaller. Therefore, bare boards are suitable for application scenarios with strict requirements on price and volume, such as special heat dissipation conditions or limited installation space.

3. Different usage scenarios

The complete power supply is mainly used for the power supply of various electronic products such as household appliances, office equipment, communication equipment, etc. The bare board is suitable for technical personnel who have high requirements for power stability, efficiency, temperature control, EMC, etc. Developers can choose suitable bare boards according to their own needs for subsequent independent development and research.

Summary

There is no difference in functionality between a bare board switch power supply and a complete power supply, mainly in terms of price, volume, and usage scenarios. For technicians, choosing to use bare boards for independent development and research can provide more flexibility and autonomy in responding to various power supply needs. Therefore, bare boards and complete power supplies should have a certain universality, as they complement each other and together play different advantages.
