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...
For high-frequency resistive voltage divider, the distributed parameter model was studied and the key factors affecting its performance were discussed. The high-frequency characteristics of typical outer structure of voltage divider were simulated by ANSYS software. According to the reflection coefficient, VSWR and return loss, an optimized structure of divider for high frequency is presented.
