Is commutator used for both ac to dc and dc to ac conversion?
Yes
What is commutation in DC machines?
It is the process of conversion of generated ac voltage into the armature of a dc generator to dc voltage at the terminal of the dc generator by use of pair of brushes and commutator. OR It is the process of conversion of given dc voltage at the terminal of the dc motor to ac voltage in the armature windings in a dc motor by use of pair of brushes and commutator.
Why DC-DC converter is used in telecommunication power supply instead of inverter?
DC-DC conversion offers the advantage of a bifurcated power source. AC can be rectified and filtered to supply power under normal conditions at say, 17VDC fed to a 9VDC regulator to power the circuit. A 12VDC battery can serve as an alternate feed to the circuit for times when the AC source fails -- and it is connected to the same 9VDC regulator. Another benefit of DC-DC conversion is isolation to the circuit from noisy events.
How you convert the 220v AC to 220v DC?
You can make this conversion if a full wave bridge rectifier is used. Make sure that the diodes are rated for the voltage that is being used.
Function of dc and ac motor?
Conversion of electrical energy into mechanical energy
What does AC-DC conversion and battery charging mean?
The voltage in your house is AC. It is in the form of a sine wave that goes positive and negative 60 times a second. To charge a battery you need DC so you do an AC to DC conversion and then apply the DC to the battery charging circuit that applies the correct charging current to the battery and checks on the state of the charge.
What current is produced in ocean thermal energy conversion dc current or ac current?
ac
Why take root mean square value?
its the maxium value 0.707 RMS. Root mean square is conversion used to give you the DC equivalent Voltage, Current, and Power of an AC system. It converts AC ability to do work and represents it as a DC equivalent value.
When changing from one unit of measurement to another a conversion factor is used to?
The conversion factor is used to made this conversion.
What DC Voltage would be need to power a universal motor that is powered by 230 V AC?
The conversion from one DC voltage to another requires electronic circuitry.
Why cant molar mass be used as a conversion factor?
It can be used as a conversion factor.
What is a backlight inverter?
a form of low voltage DC to high voltage AC power conversion circuit.
