R2S12-2415/H-R is a high-power DC-DC converter designed for applications such as radar, communication, video, automotive, and industrial. It is also suitable for charging batteries and an automated power supply. This article explains the application field and working principle of R2S12-2415/H-R.

Application Field

The R2S12-2415/H-R is a high-power DC-DC converter, which is built with advanced MOSFET technology to offer excellent power performance and reliability. Its wide operating temperature range (-40℃ to +100℃) makes it an ideal choice for various industrial and military applications. It is often used in communication systems, telecom, automotive, medical, aerospace, railway and signal processing systems. The maximum output power of the R2S12-2415/H-R is 600W with input voltage ranging from 11V to 18V. It supports low start-up current and high-efficiency operation up to 98%. This high-power converter is equipped with auto restart, over-voltage protection, under-voltage protection, and over-temperature protection for a safe operation. Therefore, its excellent performance makes it a good fit for a variety of mission-critical and harsh environment applications.

Working Principle

The R2S12-2415/H-R is based on a two-terminal forward converter topology. Working on the switching frequency of 300kHz, it operates in continuous conduction mode (CCM) and uses a synchronous rectification scheme to achieve very high efficiency. The forward converter is made up of an input stage, an output stage, a transformer, and a control circuit. The input stage consists of an input rectifier, an inductor, and upper and lower control switches that are driven by the control circuit. The output stage includes an output rectifier, a diode, and an output filter. The transformer is used to convert the input voltage into a high-voltage output voltage. It also provides electrical insulation between the input stage and the output stage, allowing them to operate independently. The control circuit monitors the output voltage and adjusts the duty cycle of the control switches in order to maintain the output voltage at a desired level. The control switches are driven by an oscillator that controls the switching speed of the upper and lower control switches. In this way, the converter is able to operate at high efficiency and deliver a highly reliable regulated output voltage. In conclusion, the R2S12-2415/H-R is a highly efficient and reliable high-power DC-DC converter. Its wide operating temperature and extended input voltage range make it a good fit for many mission-critical and harsh environment applications. In addition, its advanced synchronous rectification technology allows it to achieve very high efficiency and provide a precise output voltage.
