How do you simulate a transformer in PSpice?

How do you simulate a transformer in PSpice?

An ideal transformer is simulated using mutual inductances such that the transformer ratio N1/N2 = sqrt(L1/L2). The part in PSpice is called TFRM_LINEAR (in the Analog Library). Make the coupling factor K close to or equal to one (ex. K=1) and choose L such that wL >> the resistance seen be the inductor.

How do you add dependent current 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 voltage controlled current source?

Glossary Term: voltage-controlled-current-source Definition. An amplifier that converts a voltage to a current. Also known by several other terms (see synonym list). One synonym is OTA, or operational transconductance amplifier, a term that marries the terms transconductance amplifier and operational amplifier.

What is voltage controlled voltage source?

Voltage-controlled voltage source (VCVS)Edit This is a voltage source whose value is controlled by another voltage elsewhere in the circuit. Its output will typically be given as. , where A is a gain term and Vcis a control voltage.

How do you make a transformer in OrCAD?

Linear transformers are created in OrCAD Capture and PSpice A/D using multiple occurrences of the common inductor symbol L and the K_Linear symbol. Both symbols are located in the Analog symbol library.

How does a DC current transformer work?

The transformer is periodically saturated by the excitation current, even without any AC measured current. In this case, the CT works in the proper fluxgate mode. This makes the response to DC current more stable and less dependent on the value of the AC current.

How do you use Kbreak in PSpice?

To define your own CORE model parameters, do the following steps:

  1. Place KBREAK core symbol.
  2. Select Edit > Edit PSpice Model.
  3. Enter the model parameters and a new model name, if desired. The default model name will be kbreak. The model will be saved to a local library named .lib.

Why DC current is not used in transformer?

As mentioned before, transformers do not allow DC input to flow through. This is known as DC isolation. This is because a change in current cannot be generated by DC; meaning that there is no changing magnetic field to induce a voltage across the secondary component.

Is there a DC current transformer?

The DC Current Transformer (DCCT) is a type of DC-capable ‘current transformer,’ which produces an output current proportional to the input current – all the way down to DC. This technology is commerically available, and offers amazing accuracy: DC offset and gain accuracies of 10 ppm or better (that’s 0.001%).

What is current controlled current source?

A current source that depends on a voltage input is generally referred to as a Voltage Controlled Current Source or VCCS. A current source that depends on a current input is generally referred too as a Current Controlled Current Source or CCCS.
