2014 low-frequency transformer is now the future is ok, the feeling is now doing more switching power supply, the last low-frequency transformer will be replaced
Can not replace, in the audio amplifier, high voltage transformer and other fields, or have a unique advantage.
Low-power silicon steel transformer transformer basic prospects bleak, quality is not good, and gradually disappear. CCC seems to make life difficult.
1, low-frequency transformers will not be replaced;
2, low-frequency transformer without switching power supply pulse interference;
3, low-frequency transformer with a variety of power grid pulse interference;
4, low-frequency transformer with switching power supply can not counter the anti-surge ability, especially lightning;
5, low-frequency transformer production of linear power supply has the best introduction of ripple performance;
6, low-frequency transformer output can use low-voltage switch chip, with isolation at the same time also has a high efficiency;
In the industry, low-frequency transformers can be a good isolation from a variety of high-power inverter, servo, SCR control caused by interference.
Not the same thing.
Simply put, the transformer is a circuit of electronic components, and switching power supply is composed of a number of electronic components can achieve the corresponding power conversion circuit.
That is, from the function:
Different switching power supply can be a variety of different forms of electricity into another form of electricity, such as:
Can complete the AC and DC high / low voltage conversion; can complete the AC high / low frequency conversion; can complete the AC / DC conversion and so on. (Switching power supply which can use the transformer as a circuit component)
And if only a well-designed transformer as an electronic component, it can only achieve a fixed frequency AC high / low voltage conversion.
