Suggest an ideal to convert a full wave bridge rectifier to a half wave rectifier by changing the connecting wire/s. Draw the diagram and explain your answer.

Explanation

The circuit diagram of a full wave rectifier is given here. In one half cycle we get output due to `D_(1)` because it is in forward bias and `D_(2)` is in reverse bias. However, in next half cycle we get output due to `D_(2)` because now it is in forward bias and `D_(1)` is in reverse bias.

If in the circuit shown Y point is directly connected to point B, the arrangement will behave as a half wave rectifier. It is because in one half cycle when `D_(1)` is in forward bias, we shall get output across `R_(L)`. However in second half cycle we do not get any output because now circuit is not completed. So the arrangement acts as a half wave rectifier only.
