hive pulsating dc as input to current source in matlab

To model a current source in MATLAB Simulink, we can use the Controlled Current Source block in SimPowerSystems library and connect it to the rest of the system. This block models a DC current source, so to input pulsating DC we have to pass that DC voltage as its input.

The general steps to model a controlled current source are as follows:

1. Open a new Simulink model.
2. From the SimPowerSystems library, select the Controlled Current Source block and place it on the model.
3. Connect the input voltage to the input port of the Controlled Current Source block.
4. Set the desired current magnitude in the block parameters. This can be constant or changing with time, depending on the requirements.
5. Run the simulation to observe the output current.

Here is an example Simulink model to input a pulsating DC voltage to a current source:

In this model, a Pulsed Sine Wave block generates a pulsating DC voltage and passes it to the Controlled Current Source block, which generates a current proportional to the input voltage.

I hope this helps!
