All three quantities are now functions of the "Rload" variable. Once simulated let us now look at the voltage, current and power on the load side. It obtains the maximum value of the computed DC power and then evaluates the value of load resistor value which causes the maximum power on the load side. the parameter "Rload" which is the same we put into the "R" property of the load resistorĪlso another equation block has been placed on the schematic.The parameter sweep box in the figure has been setup to

Afterwards place the "Parameter sweep" from the "simulations" category on the schematic as shown in the below figure. Let's name it "Rload" and putting this variable name into the "R" property of the load resistor. The parameter should be the load resistance value. Lets answer this question by a parametric analysis of the given circuit. This means there is no power consumed as well. But does it also increase the DC power on the load side infinitely? With an infinite high load resistance there would be no current at all. Thus, increasing the load resistance would decrease the current and increase the voltage. With these results at hand it seems that lowering the load resistance increases the current, but decreases the power we obtain from the generator. Setting the load resistors resistance value to R=25\Omega and adding the "DCpower" result to the table we obtain the following diagram.Īs expected we get a higher current and a lower voltage at the load side since we decreased the resistance. In order to compute the DC power in the load resistor the following equation is added. An equation block is inserted on the schematic area using the icon or using the "Insert" menu by activating the "Insert Equation" item.

The user can add computation formulas on a schematic in order to let the simulator perform e.g. Simulating the schematic gives us 6V at the "out" node and 120mA through the "IProbe" current probe resulting in a power of 720mW on the load side as depicted in the result table below.

The current probe "IProbe" has been taken from the "Components" tab in the "probes" category and the dashed line separating generator and load side and the describing texts are taken from the "paintings" category. In the following figure a circuit schematic is depicted consisting of a generator with an internal resistance of 75\Omega on the left hand side and a resistive load of 50\Omega on the right hand side.

A very similar schematic is now used to introduce the concept of parametric analyses, the use of post-processing equations and how to use markers in x/y-plots. In the DC Simulation tutorial it was shown how to setup a schematic including a simple DC simulation. It is especially useful for analyzing the influence of component properties to circuit response.

It is possible to convert all equations in a document to the Professional or Linear formats, or a single equation only, if the math zone is selected or the cursor is in the equation.The example guides the reader through the process of setting up a parameter sweep. The linear option will display the equation in either UnicodeMath format, or LaTeX format, which can be set in the Conversions chunk. The Linear option displays the equation as source text, which can be used to make changes to the equation if needed. The Professional option displays the equation in a professional format optimized for display. Just choose a structure to insert it and then replace the placeholders, the small dotted-line boxes, with your own values. The Structures group provides structures you can insert.
