Abstract
In order to facilitate the testing needs of electronic engineers, a multi-channel isolation adjustable switching regulated power supply controlled by an STM32 single-chip microcomputer is designed [1]. The power supply is programmable and adjustable by a single-chip microcomputer, and the humanized display operation interface is combined with the high efficiency of switching the power supply. It can realize three channels of 30v2a isolated output, and realize one channel of 90v2a or 30v6a output through a relay automatic switching series-parallel combination, to maximize power density. The power supply has the characteristics of high integration, small volume, large power, large adjustable range, high precision, and high efficiency. It can be applied to the debugging and operation of most electronic equipment.
