用瞬時比較法研制交流穩壓電源

摘要：瞬時比較法制作交流穩壓電源的基本原理是采用輸入電壓與參考電壓進行比較找出其波形的不足，對輸入電壓進行修補，通過改變控制電壓以改善輸入電壓波形、穩定幅值，從而達到輸出電壓穩定的目的。其實質是利用小功率的控制電源得到大容量的穩定電壓輸出，使用該技術研制的交流穩壓電源具有廉價、指標高、成本低、易控制的特點。 敘詞：交流穩壓電源 瞬時比較 波形修補 控制電壓 Abstract：The basic principle of The instantaneous comparison test manufacture voltage-stabilized source's is to compare the input voltage with the referenced voltage to find out the shortcoming of the waveform and to mend the input. we can change the control voltage to make the input voltage waveform better and get a steady amplitudethus achieves the output voltage stable goal.Its essence is uses the small control power source to obtain the large capacity stable outputthis kind of A.C. stabilized voltage supply has the advantages over others in low price , high target and being easy to control.
