开关电源是利用现代电力电子技术,控制开关管开通和关断的时间比率,维持稳定输出电压的一种电源。由于拥有较高的效率和较高的功率密度,开关电源在现代电子系统中的使用越来越普及。开关电源高频化、模块化和智能化是其发展方向。其中,步进可调、实时显示是开关电源智能化研究方向之一。现设计开关电源,技术指标为:输出电压30V至36V可调,最大输出电流2A,有过流保护功能,能对输出
Switching power supply is the use of modern power electronics, control of the switch on and off the time ratio, to maintain a stable output voltage of a power supply. Due to its high efficiency and high power density, switching power supplies are becoming more and more popular in modern electronic systems. High-frequency switching power supply, modular and intelligent is the development direction. Among them, stepping adjustable, real-time display is one of the intelligent switching power supply research. Switching power supply is now designed, technical indicators: the output voltage adjustable 30V to 36V, the maximum output current 2A, over-current protection, the output
