Summary:
With the continuous maturity of the application of single-chip technology in the field of digital control, the introduction of single-chip microcomputer into the research and development of DC stabilized power supply has become an important topic in power supply research. The power supply is designed to use the AT89S51 single-chip microcomputer as the system main controller, and the AD7543 chip as the output voltage control adjustment module. The DC regulated power supply adopts digital regulation technology, and its output voltage adjustment range is 5V~15V, the stepping voltage level is up to 0.1V, and it has fault protection and alarm functions such as short circuit and overcurrent, which is not only flexible, but also convenient for maintenance and repair. The system has low cost and strong scalability, and is especially suitable for the field of digital control with fast response and high precision.
