Description

The Exponential Voltage Source block represents a voltage source whose output voltage value is an exponential pulse as a function of time and is independent of the current through the source. The following equations describe the output current as a function of time:

Vout(0≤Time≤TDR))=V1Vout(TDR<Time≤TDF)=V1+(V2-V1)*(1-e-(Time-TDR)/TR)Vout(TDF<Time)=V1+(V2-V1)*(e-(Time-TDF)/TF-e-(Time-TDR)/TR)

where:

  • V1 is the Initial value, V1 parameter value.

  • V2 is the Pulse value, V2 parameter value.

  • TDR is the Rise delay time, TDR parameter value.

  • TR is the Rise time, TR parameter value.

  • TDF is the Fall delay time, TDF parameter value.

  • TF is the Fall time, TF parameter value.

Value of the output voltage at time zero, in V.

Asymptotic value of the output voltage when the output is high, in V.

Rise time delay, in s.

Time it takes the output current to rise from the Initial Value, V1 value to the Pulse Value, V2 value.

Fall time delay.

Time it takes the output current to fall from the Pulse value, V2 value to the Initial value, V1 value.

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.
