Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to an intelligent DC stabilized power supply. Background technique [0002] DC stabilized power supply is a common electronic instrument, widely used in electronic circuits, teaching experiments and scientific research and other fields. Most of the currently used DC stabilized power supplies are linear power supplies, which are composed of discrete components. They have large volume, low efficiency, poor reliability, inconvenient operation and insufficient self-protection function, so the failure rate is high. With the rapid development of electronic technology, the performance requirements of various electronic and electrical equipment for regulated power supplies are increasing, and regulated power supplies are constantly moving toward miniaturization, high efficiency, low cost, high reliability, low electromagnetic interference, modularization and Intelligent direction de...
