The LED switching power supply has a circuit to control the switching tube for high-speed switching and cut-off. It converts direct current into high-frequency alternating current to transform the converter to produce one or more sets of voltages required! The reason for converting to high-frequency alternating current is that the efficiency of high-frequency alternating current in the transformer circuit is higher than the commercial power 50Hz or 60Hz.
Therefore, the switching power supply transformer can be made small in size, not very hot when the switching power supply is used, and the product is lower than the power frequency DC regulated power supply. If you do not change 50Hz or 60Hz into high frequency, then the switching power supply does not make any sense.
The switching power supply can be roughly divided into two types: isolated and non-isolated. The isolated type must have a switching power converter, and the isolated power supply converter does not necessarily have to be isolated.
Switching power supplies have the advantages of small size, lightweight, and high efficiency compared with conventional DC power supplies.
