DC DC Converters

DC-DC converters are electronic circuits used to convert a DC voltage from one level to another. Specifically, the YEV09T20-0G is an example of a specialized type of DC-DC converter known as an isolated forward converter. In this type of converter, energy is transferred from one DC source to another via an isolated transformer. The YEV09T20-0G converter can be used for various applications, including lighting and audio/video systems, computer memory backup, storage systems, and voltage regulation. Additionally, it has a low EMI/EMC rating, which means it produces less electromagnetic interference in the environment and is capable of electromagnetic compatibility.

Working Principle

The YEV09T20-0G converter functions by transferring energy from one electrical source to another. It involves a primary side and a secondary side, with the primary side converting the input voltage from AC to DC, and the secondary side converting the DC voltage to a new, desired level. To transfer this energy, the YEV09T20-0G uses two switches in its design. The first switch is the high-side driver, which is responsible for driving the upper end of the primary side\'s inductor. On the other hand, the second switch is the low-side driver, which is responsible for driving the lower end of the primary side\'s inductor. Furthermore, the YEV09T20-0G converter also relies on a transformer in order to transfer energy from one side to another. As the primary side\'s switches close, energy is stored in the primary side\'s inductor. This energy is then transferred across the transformer\'s primary winding to the secondary side. On the secondary side, the energy is ultimately converted and rectified to the desired level of voltage. In addition, the YEV09T20-0G isolates the primary and secondary sides from each other, meaning that even though the voltage level is changing from one side to the other, the circuits remain electrically isolated. This protects them from interference and is critical for ensuring the reliability of the converter.

Conclusion

The YEV09T20-0G is an example of an isolated forward converter, which is a type of DC-DC converter used to convert a DC voltage from one level to another. It can be used in various applications, and is highly efficient due to its low EMI/EMC rating. The YEV09T20-0G converter works by leveraging a primary side and a secondary side, with the primary side converting the input voltage to DC, and the secondary side converting the DC voltage to a desired level. Additionally, it utilizes two switches on the primary side, as well as a transformer to transfer energy from one side to the other. The circuit remains isolated, ensuring reliability and protecting it from interference.
