AC-DC Power Supply: How It Works and Its Applications
Author： ZYG Power Module Time： 2023-4-26
Introduction
AC-DC power supplies are an essential part of modern electronic devices, ranging from small portable gadgets to large industrial equipment. These power supplies convert the AC (alternating current) voltage from the mains supply to a DC (direct current) voltage that is required by the electronic device. This article aims to explain the working principle of AC-DC power supplies and their applications.
Working Principle
AC-DC power supplies typically consist of two stages: a rectifier stage and a filter stage. The rectifier stage converts the AC voltage to a pulsating DC voltage, while the filter stage smoothes out the pulsations to produce a steady DC voltage.
The rectifier stage can be implemented using different types of circuits, such as half-wave rectifiers, full-wave rectifiers, or bridge rectifiers. In a half-wave rectifier circuit, only one half of the AC waveform is converted to DC, while the other half is discarded. In a full-wave rectifier circuit, both halves of the AC waveform are converted to DC, resulting in a higher efficiency. A bridge rectifier circuit is similar to a full-wave rectifier, but it uses four diodes instead of two.
The output of the rectifier stage is a pulsating DC voltage, which still contains some AC components. The filter stage consists of a capacitor and/or an inductor that smooths out the pulsations and reduces the AC components. The capacitor stores charge when the voltage is high and releases it when the voltage is low, resulting in a more constant DC voltage. The inductor resists changes in current flow, further reducing the AC components.
Applications
AC-DC power supplies are used in a wide variety of applications, from consumer electronics to industrial machinery. Some common applications include:
1. Computers and peripherals: AC-DC power supplies are used to convert the mains voltage to the DC voltages required by the computer and its peripherals, such as the monitor and printer.
2. Mobile devices: Small and portable electronic devices, such as smartphones and tablets, use AC-DC power supplies to charge their batteries.
3. LED lighting: LED lights require a constant DC voltage to operate, which is provided by AC-DC power supplies.
4. Industrial equipment: Heavy machinery, such as CNC machines and robots, use AC-DC power supplies to power their motors and control systems.
5. Medical devices: AC-DC power supplies are used in medical equipment, such as MRI machines and ultrasound scanners.
Conclusion
AC-DC power supplies are an essential part of modern electronics, converting the AC voltage from the mains supply to the DC voltage required by electronic devices. The working principle of AC-DC power supplies involves two stages: a rectifier stage and a filter stage. AC-DC power supplies have a wide range of applications, from consumer electronics to industrial machinery and medical equipment.

Cosa è necessario considerare quando si progetta un modulo di alimentazione
Se sei un tecnico tecnico di alimentatori switching, non è necessario leggere l'introduzione del modulo di alimentazione. Quando sei ancora un principiante o stai imparando a progettare un microcontrollore, è meglio guardare parola per parola. I vantaggi della scelta di un modulo di potenza Al momento, distributori diversi hanno rilasciato una varietà di moduli di potenza diversi nel mercato di vendita, ma i tipi di tensione di lavoro, potenza, funzione e struttura della topologia dei diversi prodotti non sono gli stessi. La scelta di un modulo di alimentazione consente di risparmiare tempo di progettazione dello sviluppo e consente un rapido time-to-market, quindi un modulo di alimentazione è preferito a una soluzione integrata. 1. Ogni modulo di controllo può essere testato rigorosamente in vari aspetti per garantire che le sue proporzioni siano...
