AC-DC转换器：将交流电转换为直流电
Author： ZYG Power Module Time： 2023-4-18
An AC-DC converter is an electronic device that converts the alternating current (AC) supply voltage to direct current (DC) voltage. This type of converter is used in many applications such as power supplies, battery chargers, and lighting systems. In this article, we will discuss the working principle of an AC-DC converter and its different types.
Working Principle
The working principle of an AC-DC converter is based on rectification. Rectification is the process of converting an AC voltage into a DC voltage. This process involves the use of diodes to rectify the AC voltage. A diode is an electronic component that allows current to flow in one direction only.
The AC voltage is first stepped down to a lower voltage using a transformer. The transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction. After being stepped down, the AC voltage is rectified using one or more diodes. The rectified voltage is then filtered using a capacitor to remove any AC ripple or noise. The resulting DC voltage is then regulated to a constant voltage level using a voltage regulator.
Types of AC-DC Converters
There are two main types of AC-DC converters: unregulated and regulated. Unregulated AC-DC converters deliver a fixed DC voltage output that varies with changes in the input voltage and load. Regulated AC-DC converters deliver a constant DC voltage output regardless of changes in the input voltage or load.
Unregulated AC-DC converters are further classified into two types: half-wave and full-wave rectifiers. Half-wave rectifiers use only one diode to rectify the AC voltage, resulting in a pulsating DC voltage output. Full-wave rectifiers, on the other hand, use two or more diodes to rectify the AC voltage, resulting in a smoother DC voltage output.
Regulated AC-DC converters are also further classified into two types: linear and switching. Linear regulators use a series transistor to regulate the output voltage. They are simple and reliable but are not very efficient. Switching regulators use a switching element such as a transistor or a MOSFET to switch the input voltage on and off rapidly. They are more complex but are more efficient than linear regulators.
Conclusion
AC-DC converters are essential components in many electronic devices. They allow electronic devices to operate on DC voltage even when the power source is AC voltage. There are different types of AC-DC converters that vary in terms of their working principle, output voltage, and efficiency. Understanding the different types of AC-DC converters can help in selecting the appropriate converter for a specific application.
