either a rectifier or a motor generator
the answer is Rectifier. it converts ac voltage into dc which can apply to the dc device
The conversion from one DC voltage to another requires electronic circuitry.
As in all electronics devices that obtain power from the AC electric system, a power supply converts the AC to the DC voltage(s) needed by the electronics in the device. Depending on the needs of the device this power supply may deliver a single DC voltage or as many as several dozen different DC voltages.
A "Rectifier" converts AC current to pulsating DC current.
A Rectifier converts Alternating current into Direct current
first it converts ac to dc as rectifier But the required dc voltage is obtained by taking average of on & off DC input voltage.
the answer is Rectifier. it converts ac voltage into dc which can apply to the dc device
The conversion from one DC voltage to another requires electronic circuitry.
the work is done in the power supply box (the metal box part in the computer, the one you plug the power cord into). It converts AC to DC via transformers, rectifiers, and voltage regulators and has extra circuitry in there to make sure that the voltage doesn't ripple (with the changes in the AC voltage) or spike (e.g., when you first turn it on)
A DC to DC converter is a type of switching regulated powersupply whose input is a DC voltage, it then switches that rapidly to make AC, which is applied to the primary of a transformer, the transformer then either steps up or down the voltage as desired, the AC from the secondary is then rectified and filtered to provide the output DC voltage. Regulation circuitry measures the output DC voltage, continuously adjusting the switching circuits on the input to keep the output constant.Most switching regulated powersupplies are DC to DC converters with a simple unregulated rectifier and filter to convert the input AC to DC. Usually it is called a powersupply when it provides more than one output DC voltage or if its input is AC; whereas it is called a converter only if it provides just one output DC voltage and its input is DC. But most of the circuitry is the same in both cases.
A regulator is referring to a regulator rectifier which converts the ac voltage put out by the stator to dc voltage and regulates it to a consistent voltage usually 12-14 volts dc.

To reverse the direction of current.it converts ac voltage produced at the armature to the pulsating DC voltage at brush terminals
A "Rectifier" converts AC current to pulsating DC current.
A DC to DC converter is basically a type of switching power supply. The switcher converts the input DC to AC. A transformer is used to convert the AC to the desired voltage. A rectifier, filter, and optional regulator is used to convert the AC back to DC.
A Rectifier converts Alternating current into Direct current
An inverter simply takes a DC voltage, usually from a battery, and converts it to AC for use by standard appliances. A UPS does the same thing, but has added circuitry to charge the battery when AC utility power is available, and to automatically switch the inverter on when utility power fails.
