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. |
Answer» Solution :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 cyclewe get output due to `D_(2)` because now it is in forwardbias 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. |
