基于Z平面传输线上电压与电流的求解

Transmission Line's Voltage and Current for Solving Based on the Z Plane

针对求解传输线上任意一点电压与电流的复杂的计算量问题,本文提出了电压圆图概念和电流圆图概念。借助两种圆图将直观、方便的求出传输线上任意一点的电压与电流,计算量大为下降。两种圆图理论的建立基于经典传输线理论模型。在推导出传输线上任意一点电压与电流的计算方程之后,利用Z平面与时域角度之间的关系,导出了电压与电流在Z平面的方程,进一步借助Z平面的实轴和虚轴最终构建了电压圆图与电流圆图。

For solving the transmission line voltage and current at any point of the complex computational problems, presented in this paper circle diagram concept of the voltage and the current. It is fast, intuitive and easy to find the voltage and current at any point on the transmission lines with two circular diagrams. The calculation is of a big drop. Two graph theory is based on the transmission line theory model. Derive the transmission line's calculation equation for voltage and current at any point, using the relationship between the Z plan and the time domain, export voltage and current in the Z plane. we built a circle diagram of voltage and current with the real axis and imaginary axis of the Z plane.
