The main between an alternator along with a generator is the alternator generates alternating current (AC) and the power generator produces DC.
In the case of the actual alternator it can't operate the automotive systems or even recharge the battery till they convert the AIR CONDITIONING into DC power. Cash using an internal device known as bridge rectifier. No this kind of conversion is needed when using the generator therefore , it doesn't possess a rectifier. Both units, nevertheless can have internal or exterior voltage regulators that manage the amount of voltage sent back towards the battery.
