What is the primary side of the transformer
Step-down transformer: primary side of the high-pressure side (primary side)
Secondary side refers to the low side (secondary side)
Boost transformer: primary side of the low side (primary side)
Secondary side refers to the high pressure side (secondary side)
Introduction:
Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the purpose can be divided into: power transformers and special transformers (electric furnace change, rectifier, frequency test transformer, voltage regulator, mine transformer, audio transformers, IF transformers, high-frequency transformers, impact transformers, instrument transformers, electronic transformers , Reactors, transformers, etc.).
Explanation:
The primary side refers to the input side of the voltage, and the secondary side refers to the output side of the voltage after the voltage is converted by the transformer.
For the step-up transformer, the primary side is the low side, the secondary side is the high side;
For the buck transformer, the primary side is the high side, the secondary side is the low side.
