Three-phase staggered LLC current sharing analysis method based on three-power-supply parallel analysis model

The invention discloses a three-phase interlaced LLC current sharing analysis method based on a three-power-supply parallel analysis model, and the method comprises the steps: enabling a three-phase interlaced LLC converter to be equivalent to a three-phase parallel power supply with a coupling function, calculating the current of each phase based on a three-power-supply parallel model, and obtaining the inter-phase output current deviation according to the Kirchhoff's law; voltage at the two ends of a resonant tank circuit is obtained through a fundamental wave analysis method, and then the voltage is decoupled to a circuit of a delta structure according to a topological structure; and calculating each phase of current according to the impedance of the resonant tank circuit and defining the current unbalance degree, evaluating the current sharing performance of different topologies under different parameters based on the current unbalance degree, and comparing the conditions of different topologies to obtain
