Technical characteristics of Jingbo frequency converter

SVPWM control and over modulation technology are used to improve the voltage utilization.

The minimum harmonic narrow pulse processing method is adopted to achieve low temperature, high efficiency and long service life.

The dead time compensation technology of current prediction and correction is adopted to output the whole sine wave of current and fully improve the efficiency of the motor.

The closed-loop control of the sulfonated current is used to directly adjust the instantaneous reactive current, so that the magnetic flux of the motor is stable and the rotation is uniform without vibration, so it has the characteristics of small current and large torque.

The torque current automatic current limiting technology is adopted to realize the characteristics of the excavator and improve the overload capacity and reliability of the frequency converter.

Large design margin, mature drive and protection circuit, stable, reliable and impact resistant.
