DC DC Converters aim to convert a given DC input voltage into another DC voltage, usually with higher or lower voltage output, with a desired current rating. V72B28H250BL3 is one of the typical DC DC power converters, which is featured with its high efficiency and auto-sensing/constant current design and protection. The following passage will go in-depth into the application field and working principle of V72B28H250BL3.

Application Field of V72B28H250BL3

V72B28H250BL3 can be applied in a variety of areas. Its output features 28V and 250A, rendering it incredibly suitable for industrial current drive applications such as aircrafts, trains, ships, electric vehicles, and whatever application that requires large current output. With its IP20 design, V72B28H250BL3 is mainly applied in closed/indoor usage to prevent dust and water from entering into internal components for working safely and stably.

Moreover, due to its self-protection and other advanced features, V72B28H250BL3 can be applied in areas with high combustible and explosive risk, such as petrochemical, maritime, and aerospace industries. Compared with the traditional solutions, such as remote terminal modules with separate power modules, V72B28H250BL3 allows for considerable energy saving and can guarantee a stable supply capacity.

Working Principles of V72B28H250BL3

V72B28H250BL3 works by employing a cascade PFC (Power Factor Corrected) and AC/DC converter technique, which uses Active Front End (AFE) technology to ensure maximum efficiency and output performance. In high-power electric drive applications, the overall controllers need to offer high power density, as well as good safety, accuracy, and reliability performance.

The working principle of V72B28H250BL3 follows the classical four-quadrant dc motor drive structure. The motor speed is controlled by the application of a DC voltage source, which is created by the converter sequentially controlling several PWM(Pulse Width Modulation) controlled power switches. These power switches are configured in such a way that the output voltage, current, and frequency can be adjusted depending on the driver’s needs.

To achieve the target output voltage, current, and ratio, V72B28H250BL3 incorporates several DSP (Digital Signal Processors) to sample, analyze, and process the MCU (microcontroller unit) commands from the system. During the process, advanced electrical parameters as Power Factor, Current Harmonics, DC Offset, and Inrush Current Limit will be considered to ensure accuracy of the power outputs.

V72B28H250BL3 also has a range of unique features that make it a versatile and reliable power converter. Its Adaptive Load Sharing technology provides excellent system stability, while its on-board voltage and current sensing allow the converter to automatically adjust the output current and voltage levels for enhanced performance and flexibility. Most feature of all, its integrated external fan provides efficient thermal management performance, making it a great choice for large industrial applications.

With its innovative design, high power density, and multi-channel features, V72B28H250BL3 is a great power converter choice in high-power electric drive applications such as aircrafts, trains, ships, electric vehicles, and other related industries. Its innovative design, high efficiency and precision make it a go-to choice for complex applications with excellent performance.
