The role of electronic transformers

The role of electronic transformers In the electronics profession, you can often see the figure of transformers, the most common is used in the power supply as a conversion voltage, isolation: ① : Transformer can be divided into two kinds of boost and buck, most of the switching power supply is buck. Such electronic products are usually used in desktop power supplies, notebook adapters, mobile phone chargers, TV power supplies, rice cookers, refrigerators, induction cookers, power supplies, etc. These are AC input through the rectifier bridge, large capacitor rectifier filter, to get a high voltage direct current. ② : The boost voltage is generally used in the inverter power supply or DC-DC line, there is an emergency power supply, the battery 12V to 220V output, power supply equipment. ③: The isolation of high-frequency switching transformers is a safety requirement, in order to ensure the safety of electrical equipment. In the AC input, the switching transformer must have a safe…
