Product specification
(1) The main circuit topology adopts three-level structure and uses low-voltage power devices to realize medium voltage inverter output, with high reliability;
(2) Compared with the two-level circuit, due to the large output level, the output side is connected with RLC low-pass filter, which improves the output voltage and current waveform, and the motor runs without noise and vibration. Ordinary motors can be used without derating;
(3) The dv/dt is relatively small, which improves the electromagnetic compatibility of the frequency converter;
(4) It can automatically stabilize the voltage fluctuation on the power grid side;
(5) The starting voltage can be compensated. If the output terminal is connected with a long cable, the voltage loss on the cable can be better compensated;
(6) Power frequency / frequency conversion switch (special for electric submersible pump load) is set in the cabinet.
