        Energy storage & smart Grid PMG Converter Shore power supply Industrial power supply Power test equipment PV inverter Aviation Power supply

        400Hz medium frequency converter

        This product is designed with new technology and modular structure, such as GB7260, GJB181A-2003 and GJB572-88. It adopts digital frequency division, phase lock and waveform instantaneous value feedback control. The output waveform quality, load adaptability; has passed the State Power Electronics Product Quality Supervision Bureau Center for type testing, and has been in the aerospace, electronic technology, China Shipbuilding Heavy Industries, Weapon Industry and Equipment Research Institute, military production supporting units, military Universities and research areas widely used, and by many military customers praise.

        400Hz medium frequency converter

        1.AC parallel redundant technology

         Independent research and development exchange parallel redundancy technology, so that two or more inverters in parallel output, improve system reliability. The failure will not affect the normal load of the power supply, advanced current sharing technology so that each inverter power supply The average burden of load current, expanding the capacity of the power supply, reduce operating costs and extend the power life.

        2.Three-phase independent regulation inverter technology

        Three-phase independent regulation inverter technology is the use of three single-phase bridge transformation, and then the output by 120 degrees phase difference together, the three single-phase inverter is independent, so the three-phase output does not affect each other , With 100% unbalanced load.

        3.Frequency doubling inverter technology

        Frequency inverter technology, making high-power IGBT in the lower switching frequency, can greatly reduce the heat and improve reliability; at the same time with the same switching loss of the same frequency inverter circuit, the filter The parameter is reduced by 4 times, therefore its filter volume reduces greatly, the dynamic corresponding speed is quicker, therefore to the abrupt change load response speed is quicker, the output stability, the output precision is higher.
