A Stabilized Feed Block with Improved Quality Indicators

The main advantage of pulse-type voltage stabilizers is considered to be a high useful duty ratio, and such stabilizers allow both reducing and increasing the input voltage. This makes it possible to expand their application range. In order to achieve high operating parameters of radio stations or satellite communication systems, development of telecommunications equipment feeding systems is one of the important issues. In the article, the classic series connection of pulse voltage and compensated LDO-type voltage stabilizers is analyzed, a scheme with further improved quality indicators is proposed, where the high useful efficiency of the feeding circuit is ensured by the application of a pulse stabilizer (DC/DC converter). At the same time, thanks to the application of the LDO stabilizer, it allows to reduce the level of noise and distortions.
