摘要 電源是實(shí)現(xiàn)電能變換和功率傳遞的主要設(shè)備。在信息時(shí)代,農(nóng)業(yè)、能源、交通運(yùn)輸、通信等領(lǐng)域迅猛發(fā)展,對(duì)電影產(chǎn)業(yè)提出個(gè)更多、更高的要求,如節(jié)能、節(jié)材、減重、環(huán)保、安全、可靠等。這就迫使電源工作者不斷的探索尋求各種鄉(xiāng)關(guān)技術(shù),做出最好的電源產(chǎn)品,以滿足各行各業(yè)的要求。
UC3842是一種性能優(yōu)良的電流控制型脈寬調(diào)制器。假如由于某種原因使輸出電壓升高時(shí),脈寬調(diào)制器就會(huì)改變驅(qū)動(dòng)信號(hào)的脈沖寬度,亦即占空比D,使斬波后的平均值電壓下降,從而達(dá)到穩(wěn)壓目的,反之亦然。UC3842可以直接驅(qū)動(dòng)MOS管、IGBT等,適合于制作20~80W開(kāi)關(guān)電源。由于器件設(shè)計(jì)巧妙,由主電源電壓直接啟動(dòng),構(gòu)成電路所需元件少,非常符合電路設(shè)計(jì)中“簡(jiǎn)潔至上”的原則。

High-power switching power supply design
Abstracat Power is to achieve power conversion and power transmission major equipment. In the information age, agriculture, energy, transportation, communications and other areas Power of the film industry make a greater and higher requirements,such as energy, materials, weight reduction, environmental protection, safety and reliability. This has forced the power workers have been exploring the technology for a variety of rural customs, the power to make the best products to meet the requirements of all walks of life.
UC3842 is an excellent current-controlled pulse width modulator. If for some reason, the output voltage increases, the pulse width modulator drive signal will change the pulse width, that is, the duty cycle D, so that the average voltage drop after the chopper to achieve the regulator end, and vice versa how ever.UC3842 can control direct drive MOS, IGBT, etc., suitable for the production of 20 ~ 80W low-power switching power supply. As the device is cleverly designed, launched by the main power supply voltage directly to form circuit components required for a small, very consistent with circuit design, "simplicity first" principle.
