How do you use dependent sources in pspice?
How do you use dependent sources in pspice?
After the dependent source has been placed, left click on it to select it. Right-click on it to pop up a menu as shown in figure 3. Edit the property GAIN to set the gain (or constant) for the dependent source. Click the Apply button to set the gain and close this window.
What is a voltage controlled voltage source?
Voltage Controlled Voltage Source (VCVS) A VCVS is a voltage source where the voltage is controlled by a voltage elsewhere in a circuit. In practice, a VCVS is often used in modeling operational amplifiers (op-amps), and can also be used in modeling a voltage signal chain more generally.
What is dependent voltage?
In the theory of electrical networks, a dependent source is a voltage source or a current source whose value depends on a voltage or current elsewhere in the network. An operational amplifier can be described as a voltage source dependent on the differential input voltage between its input terminals.
What is the symbol of current dependent voltage source?
diamond-shaped symbol
Generally, an ideal current dependent source, either voltage or current controlled is designated by a diamond-shaped symbol where an arrow indicates the direction of the current, i as shown.
What is dependent and independent voltage source?
Independent source are those, whose value of either the voltage or the current to be delivered is independent of any other parameter of the network. Where as the dependent sources are those, whose value of either the voltage or the current to be delivered is dependent or controlled on other parameters of the network.
How do dependent voltage sources work?
Unlike an ideal voltage source which produces a constant voltage across its terminals regardless of what is connected to it, a controlled or dependent voltage source changes its terminal voltage depending upon the voltage across, or the current through, some other element connected to the circuit, and as such it is …
What is independent and dependent voltage current source?
An independent voltage source maintains a voltage (fixed or varying with time) which is not affected by any other quantity. They are called dependent voltage (current) sources or controlled voltage (current) sources , and their usual symbols are shown in figure 1.4.
What is the syntax for a PSpice voltage controlled voltage source?
What is the syntax for a PSpice voltage controlled voltage source? The syntax for the voltage controlled voltage source is: Ename N+ N- NC+ NC- Gain Where N+ is the positive side of the dependent source and N- is the negative side.
Where does the current go in a PSPICE circuit?
PSPICE Schematic with Current Controlled Voltage Source Note that the right side of the device goes where the voltage source appears in the circuit. The left side is connected so that the controlling current (in this case I 0 ) runs through the left side of the dependent source symbol.
Which is the positive side of a dependent voltage source?
NC+ is the positive side and NC- the negative side of the controlling voltage. The Gain can be either a positive or negative gain. In this example the dependent voltage source is called Esource and the positive terminal of the source is net 3. The negative side of the source is net 5.
What are the different types of PSpice models?
