if its already an ac y u need to convert!......Yes it need to change because in ac supply we need to change the frequency of current so ac to ac converter needed.The name of AC to AC converter is Regulator
rectifier
A diode or rectifier converts AC to DC.
Computers run off of DC power. There is an internal converter on desktops, and the large block on a laptop cord is the converter for them. On laptops, a battery runs things, batteries are DC power.
A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. PSU is a output device because it is outputting power to the rest of the device. Most personal computers can be plugged into standard electrical outlets.

an AC power plug is one that utilizes AC (or alternating current) to power a device. Alternating current is different to direct current (or DC) in the way that instead of providing a direct source of power, it alternates between negative and positive. Most devices rely on Alternating current due to circuitry reasons
A Rectifier converts Alternating current into Direct current
A "Rectifier" converts AC current to pulsating DC current.
An electrical generator, these can produce AC or DC electric current.
the answer is Rectifier. it converts ac voltage into dc which can apply to the dc device
rectifier, it is a n electrical device that converts ths high votage carrying AC to low voltage carrying DC
An alternator is a device that converts DC (direct current) to AC (alternating current). If you need to convert AC to DC, then you need a rectifier.
Assuming you mean "rectifier", a rectifier is an electrical device that converts AC, which periodically reverses direction, to DC, which flows in only one direction.
power supply
A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction.
an Inverter is an electrical device that changes DC to AC.
An inverter is an electrical device that converts direct current (DC) to alternating current (AC); the converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits.
capacitor is component used to store and release the electric charge.and also it has feature to block the dc but bypass ac.and inverter is device which converts ac to dc and then again ac
