AC-DC конвертор: Конвертирање на наизменична струја во директна струја

Автор: ZYG Power Module Time: 2023-4-17

AC-DC converters are electronic devices that convert alternating current (AC) to direct current (DC). They are commonly used in power supplies for electronic devices, such as computers, televisions, and mobile phones. The converter changes the AC input voltage to a DC output voltage that can be used to power these devices.

The AC-DC converter operates by rectifying the AC input voltage to a pulsating DC voltage. This is achieved using a rectifier, which is typically a diode bridge. The rectifier allows current to flow in only one direction, effectively converting the AC voltage to a series of positive and negative voltage pulses.

After rectification, the DC voltage still contains some ripple, or fluctuations in voltage. To remove this ripple, a smoothing capacitor is added to the circuit. The capacitor charges up during the positive voltage pulses and discharges during the negative voltage pulses, effectively reducing the amount of ripple in the output voltage.

The output voltage of the AC-DC converter is regulated using a voltage regulator. The regulator ensures that the output voltage remains constant despite variations in the input voltage or load current. This is important to ensure that the electronic device being powered receives a stable DC voltage.

There are several types of AC-DC converters, including linear and switch-mode converters. Linear converters use a linear regulator to regulate the output voltage, while switch-mode converters use a pulse-width modulation (PWM) technique to regulate the output voltage. Switch-mode converters are more efficient than linear converters, but are more complex and expensive to design.

In conclusion, AC-DC converters are essential components in electronic devices, allowing them to operate on a stable DC voltage. They use rectification, smoothing and regulation techniques to convert the AC input voltage to a stable DC output voltage. The type of converter used depends on the specific application and design requirements.

    AC-DC Converter: A Guide to Understanding and Utilizing It

    An AC-DC converter is an electronic device that converts alternating current (AC) to direct current (DC). This technology is commonly used in various electronic devices such as computers, televisions, and home appliances. The AC-DC converter works by taking the AC input voltage and using a rectifier to convert it to a DC voltage. The rectifier is usually a diode, which allows current to flow in only one direction. Once the voltage is rectified, it is then filtered through a capacitor to remove any remaining AC components. The final output voltage is then regulated to ensure that it remains constant and free from any fluctuations. There are two main types of AC-DC converters: linear and switching. Linear converters use a simple...
