哪位英语好的帮忙翻译下下面这段话,拜托了!

几乎所有电子设备中都需要稳定的直流电源。但是一般的直流稳压电源只能输出一路稳压电源,很浪费且不方便。随着电子技术的讯速发展对电源的要求越来越高。针对老式电源只能输出一路稳压电源的缺点,提出了基于集成稳压器可以输出多路电源的多路稳压电源变压器。
本设计的直流稳压电源是将电网输入的220V的交流电压变成整流电路所需要的电压,再由单相桥式整流电路将交流电压变换成脉动的直流电压,然后由电容滤波器将脉动直流电压滤除纹波,变成纹波小的电压,最后通过稳压器输出稳定电压+5V、+12V、-12、+24V和正可调的直流电压。根据多路稳压电源的设计要求,本课题采用了三端集成稳压器78系列、79系列等设计了一个可固定输出+5V、+12V、-12、+24V并能通过LM317实现输出正可调的直流稳压电源。设计中主要通过硬件来完成其稳压电源的要求,采用模拟的分立元件,通过电源变压器、整流和滤波电路以及稳压电路,实现稳压电源稳定输出+5V、±12V、+24V并能可调输出1.2~24电压。
本课题设计的稳压电源具有成本底,体积小、重量轻、使用方便和工作可靠等优点,被用于各种晶体管仪器、仪表、教学、自动控制系统与设备的直流电源。

Almost all electronic devices require a stable DC power supply. But the general DC power supply regulated power supply can output all the way, is waste and inconvenient. With the rapid development of electronic information technologies have become increasingly demanding on power. Only for the old power supply regulated power supply output of the shortcomings of the way, was proposed based on integrated voltage regulator power supply can output multiple multiple regulated power supply transformer.

The design of the DC power supply is 220V AC Power Input voltage into the required voltage rectifier circuit and then the single-phase bridge rectifier circuit converts the AC voltage ripple of the DC voltage, then the pulse capacitor filter DC voltage ripple filter into a small ripple voltage, and finally through the regulator output voltage +5 V, +12 V, -12, +24 V and is adjustable DC voltage. According to multiple regulated power supply design requirements, the subject of integration with the three-terminal regulator 78 series, 79 series, designed a fixed output +5 V, +12 V, -12, +24 V and output is achieved through the LM317 Adjustable DC Power Supply.Primarily through the design of the hardware to complete the requirements of its regulated power supply, analog discrete components, through the power transformer, rectifier and filter circuit and the voltage regulator circuit, power supply stable output +5 V, ± 12V, +24 V and can be adjust the output voltage of 1.2 ~ 24.
The subject of design and cost-end power supply, small size, light weight, easy to use and working and reliable, to be used for various transistor devices, instruments, instruction, automatic control systems and equipment, DC power supply.
