Umwandlung von AC in DC: Der AC-DC-Wandler
The world we live in is powered by electricity, and it is essential to have a steady and reliable supply of electrical power. However, the power that we get from the power grid is alternating current (AC), whereas most of the electronic devices that we use require direct current (DC). Therefore, we need a way to convert AC power to DC power, and this is where the AC-DC converter comes in.
An AC-DC converter, also known as a rectifier, is a device that converts alternating current (AC) to direct current (DC). The process of converting AC to DC involves two stages: rectification and smoothing.
Rectification is the process of converting the AC voltage to a pulsating DC voltage. This is done by using a diode, which is a one-way valve for electrical current. The diode allows current to flow in one direction only, blocking the flow of current in the opposite direction. By connecting diodes in a particular configuration, we can create a rectifier circuit that converts AC power to pulsating DC power.
The pulsating DC voltage that is produced by the rectifier is not suitable for most electronic devices, as it contains a large amount of ripple voltage. Ripple voltage is a type of AC voltage that is superimposed on the DC voltage, and it can cause electronic devices to malfunction or fail. To remove the ripple voltage and produce a clean DC voltage, we need to use a smoothing circuit.
The smoothing circuit is made up of a capacitor and a resistor. The capacitor is charged by the pulsating DC voltage produced by the rectifier, and it discharges its energy to the load when the voltage drops. The resistor is used to limit the current that flows through the capacitor and to prevent it from discharging too quickly. By using a capacitor and resistor in combination, we can create a smoothing circuit that produces a clean DC voltage with very little ripple.
In summary, the AC-DC converter is an essential component in the electrical systems that power our homes, offices, and industries. By converting AC power to DC power, it allows us to use electronic devices that require a steady and reliable source of power. The rectification and smoothing processes involved in converting AC to DC are simple yet effective, and they form the basis of many other electronic circuits and devices.

So wählen Sie einen zuverlässigen DC-DC-Stromversorger in China aus
DC bedeutet Gleichstrom. Gleichstrom ist als unidirektionaler Strom definiert. Bei einem Gleichstrom bewegen sich Elektronen ohne Richtungsänderung von einem Bereich mit negativer Ladung zu einem Bereich mit positiver Ladung. Dieser Zustand bleibt trotz Wechselstrom bestehen, bei dem sich der Strom in beide Richtungen bewegen kann. Gleichstrom kann leitende und halbleitende Materialien passieren. Elektrizität ist definiert als der Fluss von Elektronen durch einen Leiter, z. B. einen Draht. Strom baut sich auf zwei Arten auf, abwechselnd und direkt. Der Hauptunterschied zwischen Wechsel- und Gleichstrom ist die Bewegungsrichtung der Elektronen. DC-DC wird mit der Idee des Schaltnetzteils realisiert. Es gibt zwei Arten von DC-DC, Buck und Boost, die hier Buck genannt werden. Zum Beispiel,...
