How do I measure the ripple voltage, in a Buck Converter, using the scope or cursors after simulation. For some reason, the option to turn the cursors horizontally is not present. I am reading the output voltage using a voltmeter and displaying it using the scope. Please advise.
You can measure the ripple voltage by placing the vertical cursors on the desired positions and by enabling cursor analyses such as min/max/delta.
Another approach is outlined in this related forum post.
Hi Bryan,
Do you know how to read Ripple current from Capacitor using Python via RPC interface?
Kindly regards,
Ruan
Ruan, there are several approaches:
- You can either export the entire data set and find the min/max as shown in the “Buck Converter with Parameter Sweep” example.
- You can export the output of the ripple block linked in the other post at the relevant sample time(s).
- You can place the cursors using XML RPC scripts as well and get the min/max from from the cursors.
