Advantages & disadvantages of switch mode power supply (SMPS)

Following are the advantages of switch mode power supply (SMPS) are,

1. The switch mode power supply has a smaller in size.
2. The SMPS has light weight.
3. It has a better power efficiency typically 60 to 70 percent.
4. It has a strong anti interference.
5. SMPS has wide output range.
6. Low heat generation in SMPS.

Following are the disadvantages of switch mode power supply (SMPS) are,

1. The switch mode power supply (SMPS) is more complex.
2. The SMPS has higher output ripple and its regulation is worse.
3. It can be used only as a step down regulator.
4. It has only one output voltage.
5. It has high frequency electrical noise.
6. SMPS also cause harmonic distortion.
