The high-frequency IGBT rectifier model adopts the latest Ti28377DSP+FPGA digital control and T-shaped three-level conversion technology, which can ensure high-quality power supply guarantee for any data processing or industrial load, especially suitable for protecting major critical loads. VFI SS 11 (voltage and frequency independence) complies with IEC EN62040-3. This series of designs adopts new configurations, including IGBT rectifiers that ensure sinusoidal input current to replace traditional thyristor rectifiers. At the same time, products with a capacity of 300kVA and above are compatible with isolation transformers, ensuring complete electrical isolation between output and input, which can completely avoid the impact on load equipment caused by abnormal power grid conditions at the input end.
