VCVS （VoltageControlled Voltage Source）电压控制电压源。

术语介绍

GENERAL DESCRIPTION 概述

电压控制电压源是四种受控源其中之一，它是四端器件， 又称为双口元件。它有一对输入端（U1、I1）和一对输出端（U2、I2）。电压控制电压源的输出端电压则是受到输入端的控制.

Voltage-controlled voltage source is one of four types ofcontrolledsource。It is a four-terminal device，Also known as dual-port device，It has a pair ofinput terminals (U1,I1)and a pair of output terminals (U2, I2).Voltage-controlled voltage sourceoutput voltage is controlled by the input.

.　电压控制电压源的输入端电流I1=0,输出电压U2=μU1，μ被称为电压增益。它反映了电压控制电压源本身的特性。由于输入端的电流为零，所以输入端的功率为零。而输出端的电流则根据具体的电路而定

Voltage-controlled voltage source input current I1 = 0,the output voltage U2 = μU1, μ is called the voltage gain. It reflectsthe voltage-controlled voltage source their own characteristics. As the inputcurrent is zero, so the input power is zero.The output current is determinedaccording to the specific circuit.

电压控制电压源不是独立源，它的输出电压依赖于接入它的电压，所以不能单独作为电路的激励源。受控源是有源元件，在一定条件下可以向电路提供能量。在特定条件下也满足线性元件的性质.

Voltage-controlled voltage source is not an independentsource, itsoutput voltage is dependent on access to its voltage, it is notalone as theexcitation source circuit. Controlled source is an active element,under certain conditions, canprovide energy to the circuit. Undercertainconditions also satisfy the linear element in nature.
