Question 1

Animation: bridge rectifier circuit, with real diodes

This question consists of a series of images (one per page) that form an animation. Flip the pages with your fingers to view this animation (or click on the ”next” button on your viewer) frame-by-frame.

The following animation shows a bridge rectifier circuit in action. Here are some things to look for:

•  How many diodes are in conduction at any given time?

•   Is the output half-wave or full-wave?

Answer 1

Note that the diodes’ forward voltage drops create ”dead zones” in the output waveform. This is one

of the reasons that calculation of a rectifier circuit’s effective DC output voltage is complicated: it is not a

straightforward task to predict how wide these dead zones are, and to quantify the effect they have on the

output voltage.

Notes 1

The purpose of this animation is to let students study the behavior of this amplifier circuit and reach

their own conclusions. Similar to experimentation in the lab, except that here all the data collection is done

visually rather than through the use of test equipment, and the students are able to ”see” things that areinvisible in real life.
