Summary:The invention discloses a double-high distribution network harmonic suppression circuit and method based on APF-LCLLC, and relates to the technical field of power grid harmonic suppression. In order to solve the technical problem in the prior art that the work performed at present mainly aims at a certain specific load and cannot be directly applied to solve the new harmonic problem caused by the double-high distribution network, the invention provides the technical scheme that the double-high distribution network harmonic suppression circuit based on the APF-LCLLC. The circuit comprises: three capacitance-inductance units including two capacitors and one inductor; comprising two inductors; the three main circuits are respectively connected with a single capacitance and inductance unit; the three main circuits are respectively connected with the emitter electrode of the IGBT module 1 and the collector electrode of the IGBT module 2, the emitter electrode of the IGBT module 3 and the collector electrode of the
