current flows in both directions, depending on the AC voltage, i.e when ac is higher, current flows to the dc side, and vice versa
An AC generator (Alternator). A rotor is turned into a magnet by what is known as 'excitation' current. The rotor then induces AC current in the stator windings as it is rotated within it. This is AC, due to the fact that the rotor has a north and south pole, which alternately induces current in the stator windings. The exitation current is provided to the rotor via slip rings. Controlling this excitation current will also control the output power by suitable control circuitry. This is the same principle, whether it is a small domestic generator, a power station, a wind turbine, or a car alternator.
A solar powered generator involves a photovoltaic module, a deep cycle rechargeable battery and a power inverter. The photovoltaic module takes in sunlight and converts it to a DC or direct current and this is stored in the battery. The battery can then be used to power household appliances by taking the power from it and converting it to alternating current or AC with the inverter. The plug in the generator puts out AC for an appliance to use.
a generator or alternator,if the magnetic is permanent the current produced from the coil will be alternating current ac.
A generator or alternator. If the magnetic field is permanent, the current produced from the coil will be alternating current. AC. Alternators usually work the other way round. The magnet is spun inside a coil of wire. The power is taken off from the stator. The rotor is an electromagnet, fed via slip rings on the shaft. The strength of the magnet can be varied and controlled externally, to control the output voltage.
The nineteenth century British physicist, Michael Faraday invented the first electrical generator known as the dynamo.The first electric motor capable to move machinery was constructed by William Sturgeon in 1832 but in 1888 Nikola Tesla invented the first practicable AC motor and with it the polyphase power transmission system.
It may not be possible to physically convert AC generator to DC generator. What can be done is that 'Rectifier' of suitable capacity can be connected to the out put of AC generator to get DC supply.
The load conductor is connected to the load side of the generator breaker. Once the generator is up to speed the load breaker is closed and the voltage is then applied to the load.
what is the construction of ac generator
An ac generator produces ac, a dc generator produces dc, it all depends on the generator.
Through loda
Alternator and ac generator is equal
NO, generator always generating AC current,when commutator is used,at that time AC is converted in DC.and due to this generator is called dc generator.
AC supplies are not given to DC gennies. A DC gen requires a mechanical prime mover.
DC generator
You step down voltage from an AC generator with a transformer.You step down frequency from an AC generator with a motor/generator set, or with an inverter. This is not a common thing to do.
If the commutator is removed from your generator, you (if you connect slip rings) get AC supply instead of DC supply. the function of the commutator is to convert AC to DC supply and vice versa.Additional AnswerRemoving the commutator will also prevent you from connecting the output of the generator to its load. Remember, the generator's armature is spinning!
