Power supply board: the scope of power supply board is quite wide, including switching pulse power supply and coupling transformer power supply. From the literal definition, the power board is a single board to realize the power supply function; In principle, the power board is a functional circuit that can convert the input power supply voltage into various levels of working voltage required by the electronic circuit in the electronic equipment, so put them on a board, and then form a circuit board, that is, the power board.
Switching power supply: we have focused on this problem in the previous principle and technical articles. Switching power supply is composed of parallel and series. Switching power supply is a power supply system that realizes voltage conversion by switching. Switching power supply has the biggest characteristics of small volume, light weight and high efficiency, which is different from linear power supply. Switching power supply is actually a kind of power conversion circuit.
Literally, the biggest difference is that the power board is just a circuit board with no shell packaging; There are many categories of switching power supply, including bare board power supply board, waterproof power supply with shell, etc., which is a difference in appearance.
In principle, the power board is the power supply for the load; The switching power supply is a power supply system that outputs constant voltage and current. It is a power supply system that realizes voltage conversion by switching. At the same time, it is a very efficient power supply, and the output power of switching power supply is very large.
