Frequently Asked Questions:

Question: How does a switching mode power supply work compared to a linear DC power supply?

Answer: In principle, linear DC power supplies are a combination of AC input, power frequency transformer, rectifier, linear regulation and filtering. The transformer transforms the AC input voltage to the required value. The rectifier converts AC to DC with following filtering for low ripples.
A switching mode power supply is a combination of AC input, rectifier, chopping, high frequency transformer (transformers used with higher frequency can transform higher powers with same sized iron core), rectifier and filtering. The AC input voltage is usually rectified, filtered, chopped into a higher-frequency voltage by an electronic switch (hence the name switching mode power supply/SMPS) and, after transformation, rectified again to the desired voltage in the high-frequency DC link.

Question: Switching mode power supplies vs. linear DC power supplies - what are the advantage/disadvantages?

Answer: While linear DC power supplies offer a very low amount of voltage ripple, they are often big and heavy, due to the big transformers used by this technology. The voltage regulator often creates a high loss through heat energy. Moreover the input range of these devices is narrow/fixed.
The switching mode technology on the other hand can avoid some of these issues. The input range is wide/variable. They deliver high efficiency due to low heat generation. They are often small and lightweight and offer high output power. On the other hand, the switching technology can be a source for EMI, due to high frequency switching. Moreover voltage ripples can be higher compared to linear DC power supplies.

Question: What are typical applications of switching mode power supplies?

Answer: Typical applications of SMPS devices such as the Siglent SPS5000X series can be found in automotive (tests of speakers, entertainment and navigation systems), general battery testing, battery simulation, and test of consumer electronics.
Moreover, switching mode power supplies are in general used primarily to save weight, space and material for example to supply consumer and other electronic equipment because of the high power density that can be achieved.
