The invention provides a three-phase CLC immittance converter-based photovoltaic grid-connected topology and belongs to the technical field of photovoltaic power generation. The three-phase CLC immittance converter-based photovoltaic grid-connected topology comprises a parallel photovoltaic array, an LC low-pass filter circuit, a current-type three-phase bridge inverter circuit, a three-phase CLC immittance conversion circuit and a grid-connected circuit, wherein a modulation wave frequency of the current-type three-phase bridge inverter circuit is consistent with a resonant frequency of the three-phase CLC immittance conversion circuit and is equal to a 50Hz grid frequency; and generated power of the parallel photovoltaic array is controlled through regulating a phase of a modulation wave of the current-type three-phase bridge inverter circuit. The three-phase CLC immittance converter-based photovoltaic grid-connected topology has the advantages that the photovoltaic array is connected in parallel, so that additional power loss caused by local shadow shielding can be eliminated; voltage required for grid connection can be obtained without a booster circuit; a relatively high harmonic characteristic can be obtained without a filter circuit; the output power of the photovoltaic array can be controlled through controlling the phase of the modulation wave; and MPPT control is simplified.
