基于单片机的数控直流稳压电源的设计与实现

The Design and facture of a Digital Control DC Regulated Power Supply Based on Single Chip

将单片机数字控制技术,有机地融入直流稳压电源的设计中,设计并制作出一款数字化直流稳压电源。该电源采用数字调节、输出精度高,且兼备短路和过流保护及报警功能,特别适用于各种有较高精度要求的场合。利用单片机对直流稳压电源进行控制,改善了电源的性能,使用方便灵活,且成本较低,同时控制系统在软件上还可进一步改进,以扩展其功能,而并不需要增加硬件开销,从而提高电源的性能价格比。

The digital control technique of single chip microcomputer is adopted in the design of DC voltage-stabilized power supply for a multifunctional, digitalized DC voltage-stabilized power supply with higher performance cost ratio. This power source uses the digital adjustment , the output precision is high. It also has short and over-current protection and alarm, which is suitable especially in each kind situation of the high accuracy request. This design intellectualization direct-current power supply uses the self-restraint keyboard entry. The single-chip microcomputer receives voltage value information of keyboard input,and caries on processing.
