What is the working principle of switching power supply?As the world pays more attention to energy issues, the energy consumption of electronic products will become more and more prominent. How to reduce their standby power consumption and improve power supply efficiency has become an urgent problem

Switching power supply is mostly used in automation equipment as the power supply of PLC, field digital quantity, and instrument. Its appearance structure is divided into two types: one is the ordinary switching power supply, which is fixed with screws during installation.

According to the use situation, determine the voltage, current, current size, installation method, and power required by the switching power supply, and then select the switching power supply suitable for each function.

How are switching power supplies classified?According to the classification of the connection between the switching tube and the load, the switching power supply can be divided into three types: series, parallel, and transformer-coupled (parallel). Below are the details of these different types.Here

How many transformations in the output voltage of switching power supply?Switching power supply output voltage has three ways of working: direct output voltage way, average output voltage way, and amplitude output voltage way. The first one is mostly used in DC/AC inverter power supply, or DC/DC vol
