How to Create a Sinusoidal Input Signal in P-Spice?

[EugP]

Homework Statement

I need to simulate a certain circuit in p-spice, and get the transient response of a capacitor and a zener diode. I know how to do everything, except for the source voltage. The requirement is that the voltage has to be:

$$V_{in} = 10 sin (2\pi\times 50 t)$$

I don't know how to do it.

Homework Equations

The Attempt at a Solution

What I did was I just took the part called VAC, which is a simple AC source with a DC offset option. I set the AC parameter to the input voltage above, and DC offset to 0. However, I put a voltage marker right after the source, and instead of getting a sine wave, I get nothing (0 voltage).

If it helps, I attached the circuit I need to build and simulate.

$$R_1 = 10 \Omega$$
$$R_2 = 100 \Omega$$
$$C = 100 \mu F$$

It says the zener voltage is 6 V. It says nothing about D1, so I guess I will assume it is an ideal diode.

If anyone could please show me how to make any signal I want in P-spice, or at least just the one for this problem, it would be greatly appreciated.

To simulate the circuit and obtain the transient response of the capacitor and zener diode, you will need to use a voltage source that can provide a sinusoidal waveform with a frequency of 50 Hz and an amplitude of 10 V. In P-spice, this can be achieved by using the "SINE" function in the voltage source properties.

First, place a voltage source in the circuit and double-click on it to open the properties window. In the "Function" tab, select "SINE" from the drop-down menu. Then, in the "Parameters" section, enter "10" for the amplitude, "50" for the frequency, and "0" for the phase (since there is no phase shift mentioned in the problem).

Next, you will need to add a DC offset of 0 V to the sinusoidal waveform. To do this, click on the "DC Bias" tab and enter "0" for the DC offset value.

Finally, place a voltage marker at the output of the voltage source to monitor the waveform. You should now be able to see a sinusoidal waveform with an amplitude of 10 V and a frequency of 50 Hz.

As for the zener diode, you can model it as an ideal diode with a breakdown voltage of 6 V. This can be done by placing a regular diode in the circuit and setting its breakdown voltage to 6 V in the properties window.

I hope this helps you with your simulation. If you have any further questions, please don't hesitate to ask. Good luck!

To create a sinusoidal input signal in P-Spice, you can use the "SINE" function. First, you will need to define a voltage source by using the "V" command and specifying the source name, the positive and negative nodes, and the DC value (which should be 0 in this case). Then, you can use the "SINE" function to define the AC voltage source, specifying the amplitude, frequency, and phase of the sine wave.

In this case, your input voltage source would look something like this: V1 1 0 SINE(10 50 0). This will give you a 10V amplitude, 50 Hz frequency, and 0 phase sine wave. You can also add a DC offset by adding a third parameter to the SINE function, such as SINE(10 50 0 5) for a 5V DC offset.

As for your circuit, you can use the "VDC" command to define a DC voltage source for the zener diode, with a value of 6V. And for the diode, you can use the "D" command to define a diode, specifying the anode and cathode nodes and the model name (which you can leave as "D1" for an ideal diode).

Hope this helps! Let me know if you have any further questions.
