Use a transformer for the experiment.

here is a description of the transformer.

# Half-Wave Rectifier Circuit

1.)Consider building circuit below.

Determine the components needed in order to make the output ripple have a less than 1 Volt.

The output ripple can be found by

Taking AC signal from outlet equals to my input pulse width is and using say I need my current to be:

Taking

that satisfy the condition above for current so my output ripple becomes less than 1 Volts.

List the components below and show your instructor the output observed on the scope and sketch it below.

I have used the following components:





and the following input parameters:





The current through the circuit can be found as

where

.

And the current becomes

So my output ripple becomes

# Full-Wave Rectifier Circuit

Determine the components needed in order to make the above circuit's output ripple have a less than 0.5 Volt.

The output ripple in this case can be found by

Because we are now using instead of than in previous case for half-wave rectifier theoretiacally we will be able to make two times less then in previous case just by using exactly the same ellements and input parameters as before:

List the components below and show your instructor the output observed on the scope and sketch it below.

I have used the following components:





and the following input parameters:





Because now I need to replace by my output voltage now becomes two times less:
