DC-DC converters are electronic devices that specialize in the controlled conversion of electricity from one form to another. They can be used to step up, step down, as well as isolate voltages and eradicate noise and spikes. The R2S-1209/P-R is one such example of a converter. This article aims to explain its various application fields, as well as its working principle.

Applications

The R2S-1209/P-R is an isolated flyback converter and is primarily used in the conversion of high voltage AC to low voltage DC output. It is based on the IGBT technology and is designed for applications like renewable energy systems, medical equipment and SMPS for industrial purposes. It is also ideal for measuring instrumentation, safety systems, industrial automation and all other electrical and electronic products. The features of this converter include vacuum and IP67 protection, high voltage, high efficiency, Free of Charge (FOC) switch, and integrated EMI filter.

Other potential application fields of the R2S-1209/P-R converter include Charge Coupled Devices (CCDs) for astronomical imaging, distance measurement, surveillance, lighting, military applications, laser rangefinder and display devices. It can also be used in applications such as solar inverters, battery chargers and LED controllers, wind turbines, uninterruptible power supplies, ultrasonic welding, and water purification.

Working Principle

The working principle of the R2S-1209/P-R converter is relatively simple. It consists of a magnetic amplifier, power MOSFET, and a buck regulator. The power MOSFET converts the high voltage AC input into low voltage DC output, while the buck regulator maintains the output voltage. Power MOSFETs are controlled by the magnetic amplifier, which is in turn operated by the phase angle between the high voltage AC input and the amplifier output.

The power MOSFET acts as a switch which can be controlled to regulate the amount of energy transferred from the input to the output. When the power MOSFET is OFF, no energy is transferred and the output voltage is zero. When the power MOSFET is ON, energy is transferred from the input to the output and the output voltage increases. As the power MOSFET is cycled on and off, the output voltage is regulated according to the desired voltage.

The R2S-1209/P-R converter also includes a Free of Charge (FOC) switch which is a circuit that is designed to reduce transfer energy losses. It functions by disconnecting the power MOSFET when the voltage at the output is too low. This helps to reduce the continuous transfer of energy from the input to the output, resulting in an improved efficiency. Further, the integrated EMI filter helps suppress high-frequency electromagnetic interference, ensuring the safe preparation of the output voltage.

Conclusion

The R2S-1209/P-R is an isolated flyback converter that specializes in the conversion of high voltage AC to low voltage DC output. It is used in several application fields, such as renewable energy systems, medical equipment, SMPS for industrial purposes, and measuring instrumentation. The R2S-1209/P-R employs the IGBT technology and relies on a power MOSFET, magnetic amplifier, and buck regulator to regulate the amount of energy transferred from the input to output, while its FOC switch and EMI filter helps to improve efficiency and eliminate EMI interference.
