AC / DC Converters
AC/DC converters convert AC or alternating current input into DC or direct current input through a process called rectification. These electrical circuits utilize rectifiers in completing the conversion. Rectifiers make it easy for AC, which changes directions several times, to convert to CD, which flows through just one direction.
Reservoir capacitors are used for smoothing out direct current. Regulators, on the other hand, maintain voltage level.
AC/DC converters are essential components in power electronics - especially for buildings and structures that need AC/DC power supplies. They are also utilized in devices like mobile phone chargers, TVs, computers, and other consumer electronics products. The military, telecommunications, and medical sectors benefit from AC/DC converters. Industrial machinery and kitchen appliances also rely on AC/DC converters.
Types of AC/DC Converters
There are two general types of AC/DC converters: switching devices and linear devices.
- Switching devices are AC/DC converters that quickly shift from full-on to full-off state. Thus, it reduces lost energy. These converters utilize SMPS or switched-mode power supply. They may be light and small, but they are functional and efficient. However, these AC/DC converters may be a bit more complicated than the other type, and some designs rate poorly in the power factor area. Also, switching devices need to be properly suppressed or else they will produce electrical noise.
- Linear devices are simpler than switching devices. They are also larger in size but are not as efficient as the other AC/DC converter types. Linear devices are not recommended for temperature-sensitive applications because they process excess power as heat.
Here are several features that make AC/DC converters distinct:
- Short circuit, over-voltage, and over-current protection
- Passive or active power factor correction (to help increase power factor and prevent distortion)
- Ruggedized AC/DC converters that are ideal for military applications (shock-resistant and intended for hard-wearing)
- It can come with a remote on/off switch
