Sinusoidal filter

Sinusoidal filter is mainly used to solve the harmonic problem at the output of the inverter. The sinusoidal filter can convert the PWM wave output of the inverter into sinusoidal wave, reduce the voltage impact of the PWM pulse output of the inverter, reduce the traveling wave reflection phenomenon at the motor end, and prevent the insulation breakdown of the motor, resulting in cable burst. The function of long-distance transmission of frequency converter is realized.
