AC DC Converters

AC DC converters, also known as AC-DC power supplies, AC-DC inverters, AC-DC rectifiers and converters are devices used to convert the power supply between AC and DC. They are very versatile and used in a variety of applications.

The most common application of AC DC converters is in the conversion of AC power to provide higher output voltage for the operation of electrical equipment such as computers. AC power is usually provided in either 110 volts or 220 volts as used in households. However, the electronic equipment typically needs 12 volts or higher to operate. The AC-DC converter can be used to increase the voltage to the proper level for the electronic equipment to work.

Another common application for AC-DC converters is in the conversion of DC power to AC power. This is often seen in solar power applications, where solar energy is converted to AC power of household voltages. Various types of converters can be used for solutions ranging from small devices that can be mounted on the home\'s rooftop to larger scale off-grid systems for powering a variety of DC devices such as calculators, telephones and portable lights.

AC-DC converters are also commonly used in the operation of emergency lighting system, which must remain constantly supplied with DC power. The AC-DC converter is used to convert AC power from an emergency generator or standby battery system to provide an uninterrupted supply of power for the lamp.

There are a variety of top 100-112 AC DC converters used in various applications. It is important to understand the purpose of each type of converter and how it works to choose the right one for the application.

Types of AC DC Converters

The two most common types of AC-DC converters are the high-voltage and low-voltage. The high-voltage converters are used to convert AC power to a higher voltage, typically anywhere from 24 volts up to 600 volts. Low-voltage converters are used to convert the higher voltage AC power to a lower voltage such as 12 volts or 24 volts. There are also a variety of specialized AC-DC converters used for various applications, such as dimmers, AC-frequency converters, and AC-current converter.

Working Principles of AC DC Converters

The basic working principle of AC-DC converters involves the conversion of the alternating current (AC) power source to direct current (DC). This is accomplished by passing the AC power through a series of rectifiers which convert the AC electricity into DC electricity. Depending on the application, the DC output may need to be further processed to achieve the required output voltage, which is often accomplished using a voltage regulator or magnetic amplifier.

For example, if the AC source is a 110 volt power supply, it is first passed through a rectifier that converts the AC power to DC power with a voltage of 110 volts. This is then passed through the voltage regulator which can adjust the output voltage to precisely the required 12 volts. This regulated DC output can then be used to power the electrical equipment or other application.

The regulation of the output voltage, and even the conversion of AC to DC, is often done on the fly, making modern AC-DC converters versatile and easy-to-use devices. This on-the-fly capability allows the AC-DC converter to seamlessly switch between AC and DC power sources or adjust the output voltage, all without damaging the attached equipment.

Summary

AC-DC converters are devices used to convert the power supply between AC and DC. They are very versatile and used in a variety of applications, including conversion of AC to higher output voltage, conversion of DC to AC, and operation of emergency lighting system. There are a variety of top 100-112 AC DC converters used in various applications. The basic working principle of AC-DC converters involves the conversion of the AC power source to DC through rectification and, if needed, further processing using a voltage regulator or magnetic amplifier to produce the correct output voltage.
