Vargeneraatorid
Vargeneraatorid, also known as car generators, are devices that produce electrical energy to charge a vehicle's battery and power its electrical systems. These are essential components in all modern automobiles. The generator is typically driven by the engine's crankshaft via a belt. As the engine runs, the generator rotates, creating an alternating current (AC) which is then converted to direct current (DC) by a built-in rectifier, commonly using diodes. This DC power is then regulated by a voltage regulator to maintain a stable output, preventing overcharging or undercharging of the battery. Early vehicles used dynamos, a predecessor to the alternator, which also produced DC power but were less efficient and heavier. Modern vargeneraatorid are primarily alternators due to their higher efficiency and power output, especially at lower engine speeds. A malfunctioning generator can lead to a dead battery, dimming lights, and eventual engine stalling.
