Introductions
A hypothetical ideal switched mode power supply dissipates no power. Voltage regulation is achieved by varying the ratio of on-to-off time (also known as duty cycles).
In contrast, a linear dc power supply regulates the output voltage by continually dissipating power in the pass transistor. This higher power conversion efficiency is an important advantage of a switching dc power supply.
Switched-mode dc power supplies may also be substantially smaller and lighter than a linear dc supply due to the smaller transformer size and weight.
