Description

The Sinusoidal Voltage Source block represents a damped sinusoidal voltage source whose output voltage is independent of the current through the source. The following equations describe the output as a function of time:

$$\begin{array}{l}{V}_{out}\left(Time\le TD\right)=VO\\ V_{out}\left(Time>TD\right)=VO+VA*e^{-\left(Time-TD\right)*DF}*\sin \left(2\pi *FREQ*\left(Time-TD\right)\right)\end{array}$$

where:

• V0 is the Voltage offset, VO parameter value.

• VA is the Sinusoidal amplitude, VA parameter value.

• FREQ is the Sinusoidal frequency, FREQ parameter value.

• TD is the Time delay, TD parameter value.

• DF is the Damping factor, DF parameter value.

Ports

Conserving

+ — Positive voltage

electrical

Electrical conserving port associated with the sinusoidal voltage source positive voltage

- — Negative voltage

electrical

Electrical conserving port associated with the sinusoidal voltage source negative voltage

Parameters

Voltage offset, VO — Voltage offset

0 V (default)

Magnitude of the time-independent part of the output voltage.

Sinusoidal amplitude, VA — Sinusoidal amplitude

0 V (default)

Magnitude of the sinusoidal part of the output voltage.

Sinusoidal frequency, FREQ — Sinusoidal frequency

1e6 Hz (default)

Frequency of the output sine wave. The value can be less than 0.

Time delay, TD — Time delay

0 s (default)

Time at which the sine wave first starts. A value less than 0 indicates a phase shift of 180 degrees.

Damping factor, DF — Damping factor

0 1/s (default) | nonnegative scalar

Exponential damping factor for the sine wave to produce the output voltage. If DF is greater than or equal to 0, the exponential part of the equation is always damping for time greater than TD. The value must be greater than or equal to 0.
