Direct Current Generators: Quick Book
ISBN: 9781508497028 / Angielski / Miękka / 2015 / 52 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. A direct current generator, or DC generator, produces a voltage of constant polarity, which means the voltage and current do not change over time. DC generators are basically AC generators whose output voltage is switched the other way round at the proper moment, so that the direction of the voltage is always in a single direction. The AC generator uses slip rings to transfer the current to the electrical circuit, while the DC generator uses a split-ring commutator. Generators can be very small or quite huge. Commercial DC generators are commonly found in traction applications like subways...
