What is the advantage of SMPS

The biggest advantage of SMPS is that it is not big and heavy like a transformer, but smaller and lighter.

It emits much less heat as compared to transformer but it also depends on its ability to work.

The biggest disadvantage of SMPS is that its working is more complicated, which is very difficult to understand, if the SMPS ever fails, then we can buy a new SMPS for the cost of making it, that too with one year warranty.

SMPS also has a bad effect on our health as it produces high-frequency and due to high frequency energy it can also cause harmonic distortion.
