DC DC Converters: RDC2072S15 Application Field and Working Principle

DC-DC converters are compact, efficient power conversion devices, utilized for switching and amplifying electrical power from one voltage or current level to another. The RDC2072S15 is among the most technologically advanced of these offerings; it is a power factor corrector (PFC) and DC/DC converter, based on the latest cold cathode switching technology, and designed for server power supplies. The RDC2072S15 combines the fields of PFC (Power Factor Correction) and DC/DC power conversion in a single device, providing a total solution with next-generation performance levels for server power needs. This paper will discuss the RDC2072S15 application field and its working principle. It begins by describing the field of PFC, then goes into greater detail on the RDC2072S15\'s capabilities and advantages.

Introduction to Power Factor Correction (PFC)

Power Factor Correction is the process of regulating the current and voltage in an electrical circuit to accommodate a variety of conversion needs. it deals primarily with the “power factor” – the ratio between active (working) and reactive (surplus) power, which impacts operation efficiencies in terms of current and voltage. It is important when considering applications such as servers that the power factor is optimized to ensure the most efficient performance.

The RDC2072S15 Application Field and Working Principle

The RDC2072S15 offers greater power efficiency due to its PFC/DC operation. It offers below 25% total harmonic distortion (THD) at full load, meaning a smooth and accurate power conversion. It also requires fewer external components thanks to its integrated functions such as its 600V MOSFET, as well as its input under-voltage lockout module.The RDC2072S15 also offers an additional benefit in robust protection features that guard against output overload, over-voltage, over-temperature, short-circuiting, and other external conditions.The principle of operation that allows the RDC2072S15 to achieve such superior efficiency is based on its unique boost controller design and associated gate driving architecture. The boost controller handles voltage conversion, from the input level to the output level, and employs a cold cathode switching technology that is much faster than a conventional switching device. This enables it to balance the primary and secondary switching operations more efficiently, leading to greater power efficiency. The gate driving architecture of the RDC2072S15 also adds to power efficiency, by using integrated zero voltage switching (ZVS) for both primary and secondary switching operations.

Conclusion

In conclusion, the RDC2072S15 is an exceptional example of a DC-DC converter utilizing the most advanced PFC and DC/DC power conversion technologies. With its advanced boost controller and gate driving architecture, it provides powerful protection and greater power efficiency than other power converters on the market. The RDC2072S15 is ideal for server power needs that require superior performance and reliability in a single device.
