Design of Numerical Control DC Regulating Source Based on 89S51 Single Chip Microcomputer

Single chip microcomputer STM32L151CCU6

Probe current voltage pin 420*4450 head diameter 5.0 over current current and voltage pin

Summary:
The digital control technology of the single-chip microcomputer is organically integrated into the design of the DC stabilized power supply, and a digital DC stabilized power supply is designed and manufactured. The power supply adopts digital adjustment, high output precision, and has short-circuit and over-current protection and alarm functions, and is especially suitable for various occasions with high precision requirements. The use of a single-chip microcomputer to control the DC stabilized power supply improves the performance of the power supply, is convenient and flexible to use, and has a low cost, and the control system can be further improved in software to expand its functions without increasing hardware overhead. Improve the performance and price ratio of the power supply.
