DC DC converters are electrical components designed to change a direct current (DC) voltage to a different level of voltage. The VI-23K-MV-S is one type of DC DC converter that is designed to meet the requirements of specific industrial applications, such as motor drives, solar inverters, battery management systems, and other industrial systems that demand a high level of voltage accuracy and power efficiency. This article will discuss the application field and working principle of the VI-23K-MV-S.

Application Field of VI-23K-MV-S

The VI-23K-MV-S is often used in motor drives and renewable energy systems, where it is required to efficiently convert a given DC voltage to a different level of DC voltage. The VI-23K-MV-S is also suitable for use in battery management systems, where it is necessary to reliably boost or drop the voltage to the specified level. Furthermore, the VI-23K-MV-S is often utilized in systems with sensitive and critical components, such as air conditioners, medical equipment, and military/aerospace applications, where its superior accuracy and power efficiency will ensure the quality of the given system.

Working Principle of VI-23K-MV-S

The VI-23K-MV-S DC DC converter is based on a three-phase dual-active-bridge (DAB) topology. It uses a full-bridge boost converter with an active-clamp topology and two synchronous rectifiers for full control of the output voltage. To reduce the switching losses, the VI-23K-MV-S relies on an advanced Pulse-Width Modulation (PWM) technique to adjust the output voltage. The VI-23K-MV-S DC DC converter has a wide range of input and output ratings, as well as a wide input voltage range. This ensures that the converter is suitably efficient for a variety of applications.

In order to accurately regulate the output voltage, the VI-23K-MV-S employs two independent voltage loops. For voltage control, a high-gain inner loop is used, while a low-gain outer loop is used for current limit protection. To reduce EMI interference, Pre-bias compensation is used to reduce the switching frequency. The use of this technique, combined with the use of a low-EMI power component, reduces the radiation effects even further.

The VI-23K-MV-S DC DC converter also includes features such as Soft-Start, Auto-Restart, and Constant-Voltage-Limiting (CVL). Soft-Start allows the converter to start smoothly from zero voltage, while Auto-Restart allows the converter to auto-restart if it is shut down due to a fault or over-voltage. The Constant-Voltage-Limiting feature allows the converter to self-limit its output voltage and current for improved safety and reliability in critical and sensitive applications.

Conclusion

The VI-23K-MV-S DC DC converter is a reliable and efficient solution for applications that require a wide input voltage range and accurate output regulation. With its advanced PWM technique and features such as Soft-Start, Auto-Restart, and Constant-Voltage-Limiting, the VI-23K-MV-S is an ideal choice for use in motor drives, renewable energy systems, battery management systems, and other systems with delicate components.
