Engineering Output load voltages in Bridge Rectifier circuit

AI Thread Summary
In a Bridge Rectifier circuit, incorporating a capacitor results in higher output load voltages compared to configurations without a capacitor. The capacitor's role is to smooth the pulsating DC output, leading to a more stable voltage. This stabilization effect can contribute to a higher average voltage across the load. The discussion references key equations for calculating root mean square (Vrms) and average voltage (Vavg) in the context of rectification. Overall, using a capacitor enhances the performance of the rectifier by increasing the output voltage.

Homework Statement


It appears to me that output load voltages in a Bridge Rectifier circuit with capacitor always seem to be greater than that without a capacitor.
I'm aware that the function of the capacitors connected across output in rectifiers is to remove pulsation of the DC output, so does it mean that a capacitor in place can also mean that the output load voltages are higher?

Homework Equations


1.Vrms= Vp x 0.707
2. Vavg= Vp x 0.637

Can you show us plots or other information that makes you think this?
