【摘要】 滤波能使负载电压比较平滑,而电容器是非线性元件,它的存在使整流二极管电流和负载电流发生了相位变化.对二极管整流电路引入电容后的各电流及波形进行了深入研究分析,得出了较正确的波形图;经过检验,从理论和实践上对《电子技术基础》中模拟部分的桥式整流电路中波形图,尤其是波形作了更正.更多还原

【Abstract】 Rectifying circuit converts alternating current into direct current. The conversion depends on the one-way electric conductivity of diode. Therefor e,diode is the key component in forming rectification. Because the reactor has the storage capability in the circuit,the wave filter C of the parallel electri c capacity can smooth the loaded voltage. However,the electric capacity is a no n-linear component,and it changes the position of diode current and loaded cur rent. This article conducted a deep analysis of various currents and their waves ,which were produced by the lead of diode rectification circuit. The conclusion ,hence,is that the vague concept of the rectification in the text book 《Elect ric Technology》has been correctly modified.更多还原
