The setting of the simulation parameters can be critical andĭifficult to do in order to avoid numerical convergence.

This is an important restriction on the use of complex and Implement with electrical devices such as operational amplifiers.

Lack of control elements and functions, which users must.

A wide library of commercial electric components is.

Very simple to represent any electrical circuit, in particular.

Table 1: PSpice code for simulating the boost Semiconductor parameters when they need to do so. Of PSpice is that it has very complete models for the Today, several graphical interfaces areĪvailable to simplify code generation. Table 1 shows the code defining the power circuit Information along with the identification of the component In contrast to theĪpproach in Matlab-Simulink and PSB, PSpice simulates the powerĬircuit by connecting electrical components and modeling theĮlectrical activity of these components. Simulate a variety of electrical circuits.

Using PSB can present some convergence problems.

The need for snubbers and the proper setting of their valuesĬan become a very tricky part of the simulation.

PSB has special blocks for simulating AC/DC motors.

PSB can take advantage of all Matlab-Simulink.

PSB is simpler than Matlab-Simulink for power-circuit.

Rectifier power circuit (a) and control system (b).Īn important issue for working with PSB is the need for snubbers Variables from the power circuit using special measurementįigure 3: PSB diagram for single-phase boost System, Figure 3b, is the same as the diagram you use in To do this task, you use a special library (connectors) Interconnecting several blocks representing the different powerĮlements. The electrical components are groupedįigure 3a shows how you simulate the power circuit by Power circuit interconnecting the different electrical componentsĬomprising the real circuit. By now you should see that our answer for x will be ZERO.ĭo you see what I see? Yes, I found the SAME point of intersection again, which is (0,10).Matlab-Simulink for simulating power circuits by simulating the Next: To find x, we plug y = 10 into EITHER of the original equations.

See it? See why? Here's why: A negative PLUS a positive = ZERO. In our second 3x + 2y = 20, you can eliminate 3x by multiplying -3 by EVERY term in our first equation (x + y = 10).

GOAL: Eliminate x and solve for y or vice-versa. Keep in mind that it is your choice which variable you want to eliminate first. This method deals with matching the variables to ELIMINATE or do away with one. So, our point of intersection is once again (0,10). Our second equation was \(3x + 2y = 20\) and, after substituting, becomes \(3x + 2(-x + 10 ) = 20\)ģ) Plug x = 0 into EITHER original equations to find the value of y. So, \(x + y = 10\) becomes \(y = -x + 10\).Ģ) Plug the value of y (that is, -x + 10) in the second equation to find x. Here's what these two equations look like on the xy-plane: Method 2: Solve algebraicallyġ) Solve for eaither x or y in the first equation (\(x + y = 10\)). Point (0,10) means that if you plug x = 0 and y = 10 into BOTH original equations, you will find that it solves both equations. After graphing these lines, you'll find that BOTH equations meet at point (0,10). Then, graph the two lines, leading to the point of intersection. Next, \(3x + 2y = 20\) becomes \(y = -\frac + 10\) when written in slope-intercept form. To solve graphically, it is best to write BOTH equations in the slope-intercept form or in the form: \(y = mx + b\) where m = the slope and b = the y-intercept as your first step. I will solve the question using all 3 methods. 3) We can also solve it through algebraic elimination.There are three methods to solve our sample question. Here is a sample of two equations with two unknown variables: Example If you have a linear equation and a quadratic equation on the same xy-plane, there may be TWO POINTS where the graph of each equation will meet or intersect. This meeting place is called the Point of Intersection. The solution set to any equation is the place where BOTH equations meet on the xy-plane. The following two equations are graphed on the same xy-plane: When you are given 2 equations in the same question, and asked to solve for a unique answer, you can visualize the problem as be two lines on the same xy-plane. For example, in \(y = 3x + 7\), there is only one line with all the points on that line representing the solution set for the above equation.

Systems of linear equations take place when there is more than one related math expression.
