A DC generator is a machine that converts mechanical energy into direct current electrical energy.
A longer answer
A DC generator is an electrical machine which produces direct current electricity. It must be turned by a prime mover which can be an internal combustion engine - driven, usually, by diesel oil or gasoline - or can be a turbine, driven either by superheated steam or by water falling from a reservoir. (The latter is known as "hydro-electric power generation").

used to generate the dc current ,convert mechanical energy to electrical energy
An a.c. generator, or 'alternator', is used to produce a.c. voltages for transmission via the grid system or, locally, as portable generators.
An ac generator produces ac, a dc generator produces dc, it all depends on the generator.
Alternator and ac generator is equal
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.
Induction type alternator and synchronous generator.
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.
what is the construction of ac generator
An ac generator produces ac, a dc generator produces dc, it all depends on the generator.
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.
