AC DC ConvertersThe RAC03-09SGB application field and working principle provides a reliable and efficient solution to applications requiring AC to DC conversion. The low input frequency allows for low-voltage operation of up to 16 A current, making the RAC03-09SGB ideally suited for industrial applications requiring low maintenance, long operating life and high efficiency.The RAC03-09SGB contains a hybrid control circuit with integrated high-frequency switching circuit and fast response feedback compensation to ensure stable output, independent of load, while maintaining high efficiency over a wide range input without the need for an isolated power supply. This allows it to be used in applications with significant temperature and load changes.The RAC03-09SGB utilizes a variable frequency full-bridge resonant topology from full-bridge redriver module with synchronous rectifier and output filter for voltage and current regulation. This topology consists of a full-bridge diode-rectified voltage source and four power switches. The number of power switches and the frequency of the switching can be adjusted to suit the power requirements of the application.The full-bridge resonant topology reduces conducted and radiated EMI, and ensures low noise and low harmonics, thus avoiding the use of costly and bulky EMI shielding measures. It also provides high efficiency over a wide input voltage range and over a wide load range.The RAC03-09SGB also has a built-in current-limiting and over-voltage protection circuit, in addition to over-temperature and over-current protection with a built-in analog voltage control for voltage stability.In conclusion, the RAC03-09SGB is a reliable and efficient solution for AC to DC conversion with a low input frequency. Its hybrid control circuit with integrated high-frequency switching circuit and fast response feedback compensation ensures stable output, independent of load, while maintaining high efficiency over a wide range input without the need for an isolated power supply. It has a full-bridge resonant topology for reduced conducted and radiated EMI, and built-in protections for current-limiting, over-voltage, over-temperature, and over-current.
