Power transformer
In daily life, all kinds of household appliances use different voltages. It is necessary to use low-voltage DC power supply to work in household electrical appliances. The 220V AC power is converted to low-voltage AC power by power transformer, and then rectified by diode and filtered by capacitors, direct current power supply appliances are formed. And in this process of transformation, their specific energy loss is relatively small, thus achieving the purpose of convenience and economy. TV display tubes require tens of thousands of volts to work and are supplied by "line output transformers".
