Introduction

DC-DC converters are essential elements in many electronic systems. They can be used to provide both power conversion and control, allowing designers to easily integrate different components into a working electronics system. The TEN 40-7210WIR is a specialized DC-DC converter that has application in high-level communication systems, precision measurement, and industrial control applications. This article will discuss the application fields and working principle of the TEN 40-7210WIR.

Operation and Application Fields

The TEN 40-7210WIR is a 100W, 1U output power supply capable of delivering an extremely low ripple voltage of less than 15mV at its full operating capability. Its adjustable output voltage ranges from 5V to48V. It is designed to meet the high demands of sophisticated high-end communications, measurement, and industrial control equipment. It is ultra-lightweight, extremely compact, and comes with a thermal protection that prevents overheating and short-circuiting. The power supply has a wide range of industrial applications. It is particularly suited for applications requiring high-accuracy power conversion, such as in communications and technological systems working in extreme temperatures and environments, and/or those needing high-voltage, high-current distribution capabilities. Its high-performance capability is also suitable for applications found in industrial automation, industrial control systems, medical equipment, and test and measurement applications. In addition, the TEN 40-7210WIR is rated to comply with the relevant telecommunications standards and is capable of operating reliably and safely in environments with extreme temperatures, vibration, and other forms of electromagnetic radiation.

Working Principle

The TEN 40-7210WIR utilizes a unique design that allows it to achieve extremely low rippling while still delivering a high degree of power control. This design is based on a high-efficiency two-stage primary-side switching topology. The first stage is a synchronous rectified buck converter, while the second stage is an active-clamp forward converter. Both stages work together to harvest the energy that would normally be wasted as heat. The input stage is a synchronous rectified buck converter. The input rectifier diode acts as an energy-harvesting device, converting the input voltage to a DC voltage that charges up the main output inductor. The main output inductor stores the energy until it is needed to produce the output voltage, which is then supplied to the load.The active-clamp forward converter is designed to reduce voltage rippling and provide high efficiency over a wide range of input voltages. The active-clamp switching element and auxiliary winding on the output inductor act as a clamping device, ensuring a stable output voltage with minimal rippling. The TEN 40-7210WIR also features built-in current-limiting protection, over-temperature protection, and other safety and environmental safeguards. It is designed to operate reliably in extreme temperatures and environments, as well as in the presence of electromagnetic interference.

Conclusion

The TEN 40-7210WIR is an advanced DC-DC converter designed to meet the demands of high-level communication, measurement, and industrial control applications. Its specialized design and features make it ideal for applications requiring highly efficient and accurate power conversion. Furthermore, its built-in safety and environmental features ensure reliable and safe operation in a variety of conditions.
