1.29 Divider
This component divides one voltage (the y input, or numerator) by another (the x input, or
denominator).
Vo = Vy / V x
You can limit the value of the denominator input to a value above zero by using the parameter
XLowLim. This limit is approached through a quadratic smoothing function, the domain of
which you can specify as an absolute value in XDS.
In the example shown below, the 120v RMS (339.38v peak to peak) sine wave at the Y input
is divided by a 16.96V DC voltage at the X input. The result is 339.38v (peak to peak) /
16.97V = 20v peak to peak.
If Vx is replaced with a 12v RMS voltage, in phase with Vy, the output will be 10V DC.
