an algorithm based on new circulated current model is proposed to analyze the circulating current in the multiphase LLC converter. First of all, a virtual-open concept is introduced and LLC phases are decoupled from each other, Thus, A circulating current model can be achieved from fundamental harmonic approximation (FHA). Secondly, the ac voltages on the equivalent resistor of different phases are assumed same magnitude but different angle viewing from the primary-side. From mentioned above, current sharing error can be calculated, two types calculated results are shown under twophase independent LLC converter and two-phase common inductor LLC converter. Simulation results from different input voltage levels, different resonant component tolerances, and different total load are compared. A two-phase 600W prototype is built to verify the effectiveness of the proposed analysis method

“…However, the ac voltages on the equivalent resistors are assumed to have same magnitude and angle. The rectifier circuit is equivalent three ac resistor voltages for three-phase LLC converter, it also exist coupling parameter for each phase, Thus, it is hard to get decoupled circulating current for each phase [12].…”
