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:

Vout(TimeTD)=VOVout(Time>TD)=VO+VA*e(TimeTD)*DF*sin(2π*FREQ*(TimeTD))

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.

Parameters

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

Magnitude of the sinusoidal part of the output voltage.

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

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

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.
