Soft-Start Power Supply for Amplifier Loudspeakers

Last Updated on May 5, 2022 by Swagatam 9 Comments

amp power supply slow start

The proposed slow-start power supply circuit is specially designed for power amplifiers to ensure that the loudspeaker connected with the amplifier do not generate the loud and unwanted “thump” sound during power switch ON. This also implies that the power supply will safeguard or protect the loudspeaker from the sudden inrush current transient from the […]
