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.
List the components below and show your instructor the output observed on the scope.
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.
List the components below and show your instructor the output observed on the scope.
Full-Wave Rectifier Bridge Circuit
1.) Choose R in the above circuit so the low-pass filter breakpoint is less than 60 Hz.
2.) Measure the quantities below using at least 4 different load resistors.
= power dissipated by the load resistor (don't exceed resistor power rating)
= output voltage
3.) Explain why the ripple amplitude increases as I_L increases.
