Q: What’s the basic circuit on/off power arrangement? A: It starts with a source (battery or AC line), an on/off switch, and ...

Power supplies known as "switching" power supplies are commonly used. Their name is derived from the type of circuit used to change the voltage. For more details, see transformer. See power adapter.

Abstract: Power-electronics engineers designing switched mode power supplies (SMPS) are faced with the challenges of limited space, the need to meet worldwide energy regulations, and ease of design.

The difference between high-side and low-side power switching is not apparent to many new designers but is a critical aspect ...
