DC power supplies are available in either linear or switching designs. What’s the difference between the two?
A switching, or “switch-mode”, power supply directly converts the AC to a raw DC signal. While being up to 80 percent smaller and lighter than linear power supplies, switching power supplies do generate a lot of high-frequency noise which can hinder surrounding sensitive equipment. Switching supplies are quite efficient, operating at around 80 percent efficiency.
A linear power supply uses a transformer and a series of circuits to produce a very clean DC voltage. Linear power supplies have a very low-noise profile during operation. But because of the transformer size, they are often bigger and heavier designs. Linear supplies are less efficient, operating at around 60 percent efficiency due to the residual heat they generate.
