Which Type is Right for You?
The two main types of supplies utilized are linear and switch-mode, which is also known as switching. The linear option works by correcting AC line power so that it creates DC. The DC is then filtered and regulated so that it produces current and voltage levels that can be selected by the user. While the switch-mode supply may have a similar starting process to the linear one, once the AC is filtered and regulated, it switches the DC into a high-frequency AC. From this point, it is transformed into well-regulated DC. If you have higher power requirements, then opting for switching may be a good idea. Of course, this only depends on whether your project can withstand a significant level of noise pollution. If it can’t, the linear is the way to go.
