DC DC Converters

DC-DC converters, sometimes referred to as DC-to-DC converters, are power converting devices that convert one type of direct current (DC) voltage to another. DC-DC converters are used in all kinds of electronic applications, from automotive use in computers and communications equipment and most consumer electronic devices. DC-DC converters come in many form factors and provide a wide range of capabilities and functions, from basic power regulation to complex high-density power supplies. In this article, we will take a closer look at the RP100H-11048SRW/P-HC DC-DC converter and its application field and working principle.

RP100H-11048SRW/P-HC Application Field

The RP100H-11048SRW/P-HC is a 48V output DC-DC converter with an input voltage range of 10-75V DC. It is a high current power module with a nominal output of 100A. It provides ultra-high efficiency up to 94.2%, making it ideal for use in harsh environments. The module has been designed for use in a wide range of applications such as fast charging, automotive systems, telecom, computing, industrial control and other general purpose applications.

The module has a wide temperature operating range from -40 to +100 degrees Celsius (-40 to +212 degrees Fahrenheit). It also features remote on/off control, an adjustable output voltage, true output voltage control with wide dynamic range, and very low measured EMC emissions for a high level of EMC compliance. Additionally, the module includes overvoltage protection, short-circuit protection, and is compliant with the latest international energy efficiency standards.

RP100H-11048SRW/P-HC Working Principle

The RP100H-11048SRW/P-HC employs a switched-mode approach to convert the input voltage to the desired output voltage. This type of conversion is more efficient than linear conversion, as it involves the switching of an active transistor to transfer energy from one side of a circuit to the other. The module uses proprietary control circuitry for maximum power conversion efficiency, which makes it suitable for use in wireless charging, automotive systems and other applications that require high efficiency.

The RP100H-11048SRW/P-HC works by first transforming the input voltage into a higher frequency, and then transforming it back into the desired output voltage. This process is done through a series of switches, transistors, and other components that are integrated into the module’s circuit board. The module also features a synchronous rectification technique, which helps it to achieve high efficiency levels.

The RP100H-11048SRW/P-HC also features an input current shunt circuit for regulating the output voltage under various load conditions. This allows the output voltage to remain constant even when the input voltage varies, keeping the module’s power supply stable and reliable.

Conclusion

The RP100H-11048SRW/P-HC DC-DC converter is a versatile and high-performance power module suitable for a wide range of demanding applications. It provides ultra-high efficiency up to 94.2%, and comes with a variety of protection features, making it an ideal choice for harsh environments. The module uses a switched-mode approach to convert the input voltage to the desired output voltage, and a synchronous rectification technique to maximize efficiency. Additionally, the input current shunt allows it to regulate the output voltage under various load conditions, resulting in stable and reliable power supply.
