no transformer is not necessary for rectification today most of power supplies have been made without using transformer in order to reduce weight and size of power supply.for example SMPS(switch mode poqwer supply)

What is the purpose of the transformer in the half-wave rectifier circuit?
what is the function of transformer in the half wave rectifier circuit
How a rectifier transformer deffer from a power transformer?
rectifier transformer converts acinto dc.but,power transformer convert step up or step down ac energy without changing frequency
Is there any application where center tap rectifier is preferred over bridge rectifier?
For a center tapped full wave rectifier transformer secondary gives a voltage that is 2Vm. For a bridge rectifier it is Vm.
Can you use transformer for DC supply?
No. Only Transformer could not be used for DC supply.If yoy need to have DC out put,then rectifier unit required .
Why is a transformer rectifier often prefferred for smaw?
SMAW stands for shielded metal arc welding. The rectifier used in the welding machines must be referring to this type welding.

How are is a transformer and a rectifier different?
A transformer changes the VOLTAGE of AC current (AC to AC). A rectifier changes AC to DC.
How a rectifier transformer deffer from a power transformer?
rectifier transformer converts acinto dc.but,power transformer convert step up or step down ac energy without changing frequency
Can the two end of a center tap transformer be use with out a rectifier?
The twoends of a center tap transformer cannot be used without a rectifier.
Is a transformer used in full wave rectifier?
A full wave rectifier is a component or set of components that change AC waveforms into DC. It is frequently used as part of a power supply circuit and therefore it is often directly adjacent to a transformer. However, a transformer is used to provide a suitable AC voltage and is not part of the rectifier.
4 What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A rectifier is a device that converts alternating current to direct current. A transformer is a device that changes the ratio fo current to voltage. A rectifier is found in a PC power supply.
Is there any application where center tap rectifier is preferred over bridge rectifier?
For a center tapped full wave rectifier transformer secondary gives a voltage that is 2Vm. For a bridge rectifier it is Vm.
What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A transformer is a device that changes the level of an a.c. voltage, while a rectifier is a device that converts alternating current to direct current.
Why transformer use in mid point cycloconverter?
For decrease the rectifier number
Does a transformer rectify the alternating current?
No, a transformer changes the ac to a voltage that the user requires. After that a rectifier can be connected to it to provide dc.
How does a rectifier transformer differ from a power transformer?
rectifier tr. is converting ac energy into dc energy. but power transformer converting step up or step down ac energy without changing frequency.AnswerA transformer and a rectifier are two completely-different devices. A transformer changes voltage levels, whereas a rectifier changes alternating current to direct current.There is no such thing as a 'rectifier transformer', although it is common for the output of a transformer to be rectified. Such combinations are widely-used in electronic components, where the mains supply must be changed to a low-voltage d.c. supply.The term, 'power transformer' is normally applied to step-up and step-down transformers used in the high-voltage electricity transmission system, as opposed to those used in the electricity distribution system, which are normally called 'distribution transformers'.
How can you determine the polarity of the leads of a transformer rectifier so you can connect a suitable plug?
rectifiers have two terminals.it has a circular ring printed on its body.this terminal is negative or n type.but when you connect any terminal of a rectifier to any of the leads of transformer it works reverse.e.g if u connect -ve terminal to the transformer it will give +ve potential,so the other terminal of transformer without rectifier will give -ve potential.
