Voltage-dividing type harmonic suppression device

The invention discloses a voltage-dividing type harmonic suppression device belonging to the harmonic suppression technology field. The voltage-dividing type harmonic suppression device comprises a reactor L1, a capacitor C1, and a capacitor C2. The reactor L1 is sequentially serially connected with the capacitor C1 and the capacitor C2, and then is connected between a power supply phase line and a power supply neural line. A load RL is parallely connected with the capacitor C2. The reactor L1 and the capacitor C1, which are serially connected together, are short circuit for the power frequency power supply, and the high impedance to the high frequency harmonic interference of the power frequency power supply can be provided, and the high frequency voltage-dividing capacitor C2 has the high impedance to the power supply, and then the low impedance to the high frequency harmonic interference can be provided. The most of harmonic voltage of the power frequency power supply can be distributed to the reactor L1 a
