AC DC Desktop, Wall Adapters

AC DC Desktop, Wall Adapters are used to convert alternating-current (AC) energy to direct-current (DC) energy. AC electricity is the common form of energy we use in our households, whereas DC electricity is used in electronic components to power them and run them correctly. SDI18-9-UDC-P5 is one of these adapters. To understand the application field and work principle of this product, we must first understand what AC and DC is, and what the application of AC DC adapters is.

AC/DC Basics

Alternating current (AC) is the type of energy generated and transmitted through power lines. This type of energy changes polarity, or direction, many times per second. Electrical items in the household use alternating current to function, and the AC current works in many different voltages all over the world.

Direct current (DC) works in just one direction. The voltage is always the same, and it is not affected by the increase or decrease in the current. The DC energy is required to power electronic components, such as calculators, cell phones, and computer parts. All of these items use DC energy to work correctly.

Application of Adapters

SDI18-9-UDC-P5 is one of the adapters used to convert AC energy to DC energy. This type of adapter is used for a variety of purposes. These adapters are generally used to power DC-powered items. For example, if a computer has an AC wall outlet, the adapter would allow it to be powered with DC energy. In addition, this type of adapter is commonly used for backup power, such as emergency lighting and portable radios.

Working Principle of Adapters

The SDI18-9-UDC-P5 adapter works by converting AC power into DC power, using a transformer, inductor, diode bridge, and capacitor. To do this, it uses a process known as “chop-bridge” conversion. Basically, the Adapter is fed AC power and it chops this power into an alternating waveform. Then, a diode bridge rectifies the signal by only allowing current to flow in one direction, and the capacitor helps to reduce voltage spikes. After that, the voltage is then passed through a transformer to control the voltage and amperage that is being output from the adapter.

Conclusion

The SDI18-9-UDC-P5 is one of the many AC DC adapters available for purchase. It works by converting AC power to DC power, using a simple “chop-bridge” process and a transformer, diode bridge, inductor, and capacitor. It is commonly used to power DC-powered items, as well as for backup power. Understanding the application field and working principle of this adapter is important for proper use.
