The 400Hz medium-frequency static frequency converter, leveraging multiple advanced technologies and outstanding performance, provides reliable support for various power application scenarios. It is widely used in high-performance equipment such as aircraft, aviation communication devices, and spacecraft for power supply. With the rapid development of the aviation sector, the demand for 400Hz aviation medium-frequency static frequency converters and aircraft medium-frequency static frequency converters will continue to grow. The power supply industry will also advance towards higher efficiency, greater stability, and enhanced reliability.

It employs AC parallel redundancy technology, three-phase independent regulation inverter technology, and frequency-doubling inverter technology. Among these, AC parallel redundancy technology allows two or more inverter power supplies to output in parallel, improving system reliability. If one unit fails, it does not affect the normal power supply to the load. Advanced current-sharing technology ensures that each inverter power supply equally shares the load current, expanding power capacity, reducing operating costs, and extending the service life of the power supply. The three-phase independent regulation inverter technology enables the equipment to operate normally under unbalanced loads.

By adopting frequency-doubling inverter technology, high-power IGBTs operate at lower switching frequencies, significantly reducing heat generation and improving reliability. Compared to same-frequency inverter circuits with equivalent switching losses, the parameters of the filter are reduced by four times, resulting in a much smaller filter size, faster dynamic response speed, higher output stability, and greater output precision.
