Difference Between AC and DC Generator
| Difference Between AC and DC Generator | |
|---|---|
| AC Generator | DC Generator |
| An AC generator is a device that converts mechanical energy into alternating electrical energy, such as alternating currents and alternating electromagnetic fields. | A DC generator is a device that converts mechanical energy into direct electrical energy, such as direct currents and direct electromagnetic fields. |
| Slip rings have a smooth and unbroken surface, consequently they do not wear quickly & are extremely efficient. | A DC generator’s brushes and commutators wear out quickly, leading to reduced efficiency. |
| The brushes have tremendous efficiency, thus a short circuit is highly improbable. | The brushes & commutators wear down quickly, increasing the potential of sparking and short circuits. |
| AC generators are simple to maintain and highly reliable. | DC generators require frequent maintenance & are less dependable. |
