Computer numerical control (CNC) is becoming more and more popular in the industrial field. With computerized parts becoming common, CNC machines allow for quick and exact production of components. They can handle complex shapes as well as difficult or complex geometries. However, as CNC machinery is very costly, they are not suitable for low volume production of components. That is where the use of CU20-14 application and working principle comes in.

The CU20-14 is a high efficiency AC to DC converter. It has a maximum rated current of 20A, making it an efficient device for small and medium current applications. It also has a wide input voltage range of 3.3V to 13.8V, which makes it suitable for applications in various industrial settings. The CU20-14 has two output pins, one for the positive voltage and one for the negative voltage. The device offers excellent efficiency of up to 90%, meaning that it can convert AC to DC with minimal losses.

As for the working principle of the CU20-14, it relies on a full bridge rectifier to convert the incoming AC input to a DC waveform. The full bridge rectifier splits the AC waveform into two opposite polarities. The two opposite polarities of the rectified waveform are then averaged and filtered to produce a DC voltage. The filtered DC waveform is then fed to two power switches (MOSFETs) connected in reverse polarity to each other. When power is applied to the switches, the MOSFETs are "bridged" and the current flows in both directions, resulting in a smooth DC output. This method is known as synchronous rectification.

The CU20-14 also has built-in protections such as over-voltage and under-voltage protections to ensure the safe operation of the device. It also has a built-in over-temperature protection, which is activated when the temperature of the device exceeds a certain threshold. This allows the device to shut down safely if it overheats. Additionally, the device features short circuit protection, which prevents any possibility of damage from sudden power fluctuations.

Overall, the CU20-14 is an efficient and reliable AC to DC converter for small and medium current applications. Its wide input voltage range and high efficiency make it suitable for various industrial settings. The device also comes with built-in protections to ensure the safety and reliability of the device. Therefore, the CU20-14 can be a great choice for applications requiring a reliable and efficient AC to DC converter.
