What is regulation in a dc power supply ? OR Explain unregulated power supply and regulated power supply. |
|
Answer» Voltage regulation is am important factor of a power supply. Regulation is its ability to hold the dc output steady under conditions of changing ac input or changing load. The output voltage under no-load condition (no current drawn from the supply) tends to drop to a lower value when load current is drawn from the supply (under load). The amount the dc voltage changes between the no-load and full-load conditions is described by a factor called voltage regulation. Voltage regulation = \(\cfrac{no-load \,voltage − full-load \,voltage}{full-load \,voltage}\) |
