In addition, this product is able to provide reliable power in antennas and base stations, and it is capable of providing additional power for back-up and auxiliary systems.

Working Principle

The 0RSB-30T120G is a full-bridge diode rectifier with an LLC resonant forward converter. This product is designed to operate in the two-switch forward (LLC resonant) topology, which helps to reduce switching losses and improve efficiency. The LLC resonant forward converter is capable of operating at high efficiency in a wide input voltage range of 85-265VAC. The 0RSB-30T120G also incorporates a low-pass filter, a synchronous rectifying totem pole PFC converter, and a DC-DC buck converter.

The low-pass filter helps to reduce the input current ripple at the input of the LLC resonant forward converter. Meanwhile, the synchronous rectifying totem pole PFC converter is used to ensure reliable and stable output voltage under a wide input range. The DC-DC buck converter -- also known as a voltage converter -- acts as a bridge between the input voltage and the output voltage to adjust the voltage levels. In addition to providing reliable output voltage, the device also has over-voltage, over-current, and overload protection to ensure secure operation.

Conclusion

The 0RSB-30T120G is a DC-DC converter with an LLC resonant forward diode bridge rectifier, a low-pass filter, a synchronous rectifying totem pole PFC converter, and a DC-DC buck converter. It is designed to provide reliable operation in server power supplies, telecom power supply, and industrial power applications. It offers excellent performance, high reliability, and an isolation voltage of up to 1kV. In addition, it features a wide operating range from 85 to 265VAC. By utilizing the two-switch forward (LLC resonant) topology and incorporating additional features such as the low-pass filter, the synchronous rectifying totem pole PFC converter, and the DC-DC buck converter, the 0RSB-30T120G is able to deliver reliable and stable output voltage at high efficiency.
