Pulse Voltage Source

Source of periodic voltage pulses of rectangular shape.

pulse voltage source

Description

The Pulse Voltage Source unit is a source of periodic voltage pulses that are time dependent and current independent. The output voltage as a function of time can be represented as:

where

- is the output voltage at zero moment of time;
- output voltage at high output level;
- pulse onset time;
- the time it takes for the output voltage to change from to ;
- time it takes for the output voltage to change from to ;
- output pulse width;
- pulse repetition period.

The block determines the values at intermediate time points by linear interpolation.

The specified values for and have the following effect on the block output:

If and are infinite, the block outputs a staggered response at time .
If is infinite and is finite, the block outputs a single pulse of width and infinite period.
If is infinite and is finite, the block produces a stepped response with pulses of width to every seconds.
If > , the unit makes a staggered response with pulses with a width of to every seconds.
