摘要

In the domain of power supplies, achieving high stability, minimal ripple, and a wide output range in direct current (DC) constant current sources has emerged as a pivotal research focus. These sources address the challenge of maintaining stability in high current outputs by employing negative feedback mechanisms, selecting appropriate topologies, and ensuring precise measurement of the output current. This paper aims to present an overview of various constant current sources and to delve into the critical technologies that influence output current stability, including circuit topology, feedback control algorithms, current measurement techniques, and the characteristics of power devices. In conclusion, the paper reflects on the existing challenges and difficulties in the design of stable constant current sources and offers insights into potential future trajectories for this technology.
