Hello, Apologies for the delayed response. Based on the information above, would it be reasonable to assume then that the discharge period is approximately equal to the total period, therefore creating the sawtooth shape? If so, this then gives the rms value as: peak/√3 ?

Good Afternoon Everyone, Many thanks for all of your input so far - it has been extremely helpful. I have been stuck in a bit of rut with a couple of these problems recently and this has given me a bit of confidence going forward. Based on the use of the approximation Vr = IL/fC, I end up with...

Good Afternoon BvU, Thank you for the warm welcome & for the advice regarding additional information etc. I do have a diagram - when I can get access to scanner, I will provide this. My understanding of the circuit is as follows: The transformer steps down the AC voltage at a 10:1 ratio. The...

Good Afternoon gneill, Many thanks for the warm welcome! The literature I have been given for this particular set of questions seems to use the approximation method to work out the ripple voltage. There is a question further on which requests that I use simulation software to produce a...

Hello tech99, Having read some technical literature online, I do agree with what you are saying. Unfortunately that is the value I have been given to work with.

Homework Statement I have an unregulated power supply circuit consisting of the following: Transformer, 10:1 ratio, 230VAC rms 50Hz incoming voltage Full Wave Bridge Rectifier Filter Capacitor, 1000μF Load - Resistor, 25Ω Find the following: 1) RMS & peak voltage across secondary winding of...

Hello Everyone, Name is Shaun. Currently work as an electrical engineer + on going studying to keep learning more! :)
