半波整流—滤波电路的两种不同解法

Two resolution methods of half-wave rectifying filtering circuit

结合半波整流—滤波电路,分别采用牛顿—拉夫逊法和PSPICE进行求解,均得出了正确的结果.经比较,两种方法各有所长.尤其是当电路中的非线性元件比较多,元件之间的非线性关系比较复杂,采用牛顿—拉夫逊法难以得到递推表达式时,用PSPICE求解非线性电路更具优越性.

Ab Connecting a half-wave rectifying filtering ing both the Newton-Raphson method and PSPICE. circuit, this article obtains correct results by apply- By comparison between the two methods, each has its own strong points. Especially when the circuit has many nonlinear components, as well as the rela- tionship among these components is much more complicated, the recursive formula is difficult to get. The way to resolve nonlinear circuits by using PSPICE has much advantage.
