adding Sin into simulation

Question

0 个投票

Hi,

I have voltage output signal(DC) and I want to add a sinwave into it. for exmple: If V_out=200v I want to change it in format: V_out*sin(Omega*t+phi), which Omega= 100*pi and phi=0.

How to addV_out if it changeevery monent ?

How to add sine block with that parameters ?

Thanks, Henry

Indeed, the Sine Wave block assumes constant amplitude, phase, and frequency. In your case, you want the amplitude to vary which means you should use fundamental blocks as follows:

First, you want to generate the time signal "t". To do this, you can use a Clock block, which outputs the simulation time.
Next, you can multiply that signal by frequency "Omega" and add phase "phi" to it.
Then, input that signal into a Trigonometric Function block configured with the sin function.
Finally, take that whole output and multiply it by your amplitude signal "V_out".

Hi, I built a simple DC to AC inverter. The output of that inverter is about 11 levels voltage. Adding an Low Pass filter to it, smooth the shape of the output signal an it becomes more likely as a sinusoidal.

My question is: How to synchronize that signal with the grid signal ? - for example Fgrid = 50 Hz or 60 Hz.

I understand than I need to do V_out*sin(W*t + Phi) which is: V_out = 11 level voltages. W*t = frequency grid, letsay 100*PI. Phi = 0, 120, 240 - for tree phase.

Thanks for help, Henry
