VE-2TT-MY

DC DC Converters

DC-DC converters are used in a variety of applications, ranging from solar panels to cars, to provide a regulated power supply. The basic principle of operation is to convert a high- voltage DC power source into a lower-voltage DC source, thereby providing an efficient and safe source of power. In this article we will discuss the application and working principle of the VE-2TT-MY series DC- DC converter.

VE-2TT-MY application field

The VE-2TT-MY series DC-DC converter is a reliable and robust mid-power (1000W to 4000W) full-bridge DC-DC converter designed to power a variety of applications such as industrial, aviation, marine, and automotive. It is designed to provide a highly efficient, low-noise power source with excellent EMI performance as well as very low power waste, enabling the user to obtain the highest performance from the power supply system. Typical applications include renewable energy inverters, load switching/protection devices, power supplies, and automotive electronics.

VE-2TT-MY working principle

The basic operation of the VE-2TT-MY DC- DC converter is based on a control loop. The principle of operation is to control the average current of the switching transistor, which is connected between the input voltage and the output voltage. The switching transistor is driven by a boost converter which can be operated at a frequency up to 100 kHz. The average current is determined by a reference voltage at the input of the error amplifier which compares the output voltage with a set reference voltage and produces an analog control signal, which is then fed to the power stage. This loop ensures stable operation over a wide range of input voltages, without any overshoot or ringing in the output.

The VE-2TT-MY series DC-DC converter also provides additional features such as over-temperature protection, soft-start, and over-current protection. The over-temperature protection can be used to protect against accidental over-supply of current or thermal runaway, while the soft-start helps minimize inrush current and reduces stress on the power supply components. Finally, the over-current protection can be used to prevent output short-circuiting and ensure the safe operation of the power supply system.

Conclusion

In conclusion, the VE-2TT-MY series DC-DC converter is an efficient and reliable mid-power full-bridge DC-DC converter suitable for many applications. Its operation is based on a control loop which ensures reliable output over a wide range of input voltages. Additionally, it provides additional features such as over-temperature protection, soft-start, and over-current protection, to ensure safe operation of the power supply system. Therefore, the VE-2TT-MY series is an excellent choice for reliable and efficient power conversions.
