Generating Direct Current: The AC-DC Converter
저자： ZYG 전원 모듈 Time： 2023-4-15
Direct current (DC) is a type of electrical current that flows in only one direction. It is widely used in electronics, power supplies, and many other applications. However, most of our electrical power grid is alternating current (AC), which means that the electrical current periodically changes direction. Therefore, to use AC power in DC devices, we need an AC-DC converter to convert the AC power into DC power. In this article, we will discuss how an AC-DC converter works.
Firstly, let understand the difference between AC and DC power. AC power alternates between positive and negative voltage cycles, and it flows in a sine wave pattern. On the other hand, DC power flows in a straight line, and it has a constant voltage level. Therefore, to convert AC power into DC power, we need to convert the sine wave pattern into a straight line.
The most common type of AC-DC converter is the rectifier. A rectifier is a device that converts AC power into pulsating DC power. It uses a diode or a set of diodes to allow current to flow in only one direction. A diode is a semiconductor device that acts as a one-way valve for current. It allows current to flow in one direction and blocks current flow in the opposite direction.
There are two types of rectifiers: half-wave rectifiers and full-wave rectifiers. A half-wave rectifier uses only one diode to allow current flow in one direction. It blocks the opposite direction of current flow. As a result, it generates pulsating DC power with a voltage level equal to the peak voltage of the AC power. However, this type of rectifier is not very efficient, as it uses only half of the AC power cycle.
A full-wave rectifier uses four diodes to allow current flow in only one direction. It generates pulsating DC power with a voltage level equal to the peak voltage of the AC power, but it uses the entire AC power cycle. Therefore, it is more efficient than the half-wave rectifier.
However, both half-wave and full-wave rectifiers generate pulsating DC power, which is not suitable for most DC devices. To convert pulsating DC power into smooth DC power, we need a filter circuit. A filter circuit is a device that smoothes out the pulsations of the DC power, resulting in a steady and constant DC voltage level.
The most common type of filter circuit is the capacitor filter. It uses a capacitor to store charge and release it to the load when the DC voltage level drops. Therefore, it smooths out the pulsations of the DC power and generates a steady and constant DC voltage level.
In conclusion, an AC-DC converter is a device that converts AC power into DC power. The most common type of AC-DC converter is the rectifier, which uses diodes to allow current flow in one direction. There are two types of rectifiers: half-wave and full-wave rectifiers. However, both types generate pulsating DC power, which needs to be smoothed out by a filter circuit. The most common type of filter circuit is the capacitor filter, which generates a steady and constant DC voltage level.
