Full Bridge Rectifier With Capacitor. Your capacitor will charge to the peak bridge rectifier s output voltage minus the drop through the diodes. Active 4 years 8 months ago.
This substantial peak to peak voltage between the valleys along with the peak cycles are smoothed or reimbursed by means of filter capacitors or smoothing capacitors across the output of the bridge rectifier. This smoothing capacitor is furthermore referred to as the reservoir capacitor mainly because it services similar to a reservoir tank and holds the energy in the course of the peak cycles of the rectified voltage. The main advantages of a full wave bridge rectifier is that it has a smaller ac ripple value for a given load and a smaller reservoir or smoothing capacitor than an equivalent half wave rectifier.
But this cannot be used in real life applications.
For a transformer with an output voltage of voac your capacitor should charge to somewhere around voac sqrt 2 1 4 where the 1 4 is the voltage lost across the two conducting diodes in your bridge rectifier. Amazing explanation of full wave bridge rectifier with the help of animation is presented in this video. To convert ac to dc efficiently we need full bridge rectifier which consist of four diodes.
