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.
