This exercise provides instructions for developing and using the UCM device in HYPERSIM.

Implement the following simple model in a new HYPERSIM document.

Example model before adding the UCM


Manually calculate the current and voltage of the “load _1” component. What is the current for R_2? What is the voltage for Bus_3? Measure them in ScopeView by assigning sensors to the model.
A: The current is 2 Amps. The voltage is 40 V.


Add the UCM device to the model by clicking on the UCM menu and selecting Import UCM, and then selecting the corresponding definition file.

UCM menu


Exclude the R3 resistor by right-clicking on R3 and selecting Exclude/Include and connect the UCM.

Example model with excluded R3

Set the resistor value of the UCM equal to 20 ohm as shown in the figure below.

Resistor description window


Run the model again and measure the current and voltage of load_1 component. What is the current of R_2? What is the voltage of Bus_3?
A: Current is 2 Amps. The voltage is 40 V.


Bring back the R3 component by selecting Exclude /Include. Now the model will look like this:

Model diagram with R3 included again

What is the current of R2? What is the voltage of Bus_3?
A: Current is (100/40) =2.5 Amps. The voltage is 10*2.5=25 V.
