EnglishGenerally speaking, power board and switching power supply are not two opposite terms, and there is no comparison in fact, but some students will ask this question in the process of learning and designing switching power supply. We illustrate the difference between switching power supplies and power strips from the definition and scope differences between power strips and switching power supplies.
Power board: The range of power board is quite wide, including switching pulse power supply and coupled transformer power supply. Literally speaking, the power board is a single board that realizes the power supply function; the power board is in principle a functional circuit that converts the input power supply voltage into various working voltages required by the electronic circuits in the electronic equipment, so put them together. board, and then form a circuit board, the power board.
Switching power supply: We have analyzed this issue in previous technical articles. The switching power supply consists of parallel and series. A switching power supply is a power supply system that realizes voltage conversion through switches. Different from linear power supply, switching power supply is characterized by small size, light weight and high efficiency. A switching power supply is actually a power conversion circuit.
Literally speaking, the biggest difference is that the power board is just a circuit board, without a shell package; there are many types of switching power supplies, such as bare board power boards, waterproof power supplies with shells, etc., which are different in appearance.
In principle, the power supply board is the power supply that provides the load; the switching power supply is a power supply system that outputs constant voltage and constant current, and realizes voltage conversion through switches. At the same time, it is a very efficient power supply with a very large output power.
The power board and the switching power supply are not opposite, but some students still have such doubts in the process of learning the switching power supply. For the power board and switching power supply, I hope everyone can only clearly distinguish the definition and principle.
