1) The main circuit topology adopts three-level structure, using low-voltage power devices to achieve medium-voltage inverter output, with high reliability.

2) Compared with the two-level circuit, the output voltage and current waveform is improved due to the many output levels and the RLC low-pass filter connected to the output side. The motor runs noiseless and vibration-free.Ordinary motor can be used, and do not need to drop.

3) DV/DT is relatively small, which improves the EMC characteristics of the frequency converter;

4) It has the function of automatic voltage stabilization on the voltage fluctuation of the grid side.

5) Starting voltage can be compensated.If the output end is connected to a long cable, the voltage loss on the cable can be compensated.

6) The cabinet is equipped with power frequency/frequency conversion switch (special for load of submersible electric pump).
