Pressing A on the keyboard changes the potentiometer wiper position which controls the voltage at the Control pin, controlling your pulse width.

When it passes 0.5V, it will trigger the one shot.

The function generator outputs a triangle wave.

The advanced spreadsheet view, toolbox, and design wizards help you easily manage, control, and define any board layout. When set to low, the circuit will be in operation mode. With its automated functionality, you can quickly complete a design. When the input is set to high the output should be zero. When simulating the example circuit below, please note the following: Since this table has a piecewise property, when the input to the Control pin is 2V the output pulse will be 2ms and if it is 4V the pulse will be 4ms. When the input is at 3V the output pulse will be 3ms. When the voltage to the control pin is 1V, the output pulse is 3ms. In the example circuit, the following values were entered:

The input voltage at the Control pin is used to determine the output pulse width.

When the voltage at this pin reaches the define value, it will trigger the component.

The Clock Trigger Value sets the clock pin threshold value.

Double click on the component and select the Value tab.

To set the Controlled One Shot component

You can find this component under the Sources group and Controlled Voltage Sources family.įrom left to right the pins at the top of the symbol represent:Īll pins on the bottom of the component are usually tied to ground. The Controlled One Shot is a very versatile component which can be used to create a PWM signal. If you are using an older version of Multisim you can simulate a PWM using the Controlled One Shot component. This updated database includes power controllers such as models of phase angle controllers and PWM controllers. Multisim 12 has updated its components database with 92 component models that are widely used in the design of power and electromechanical devices.
