Abstract

This work suggests a three-phase interleaved multi LLC resonant converter with variable frequency control. The suggested converter yields high gain of the voltage with Zero Voltage Switching (ZVS) for all primary active switches. The converter accomplishes significant load variation using variable frequency control, whereby the converter gain is studied with regards to the tank impedance that is based on the relation of the switching frequency to the resonant frequency. Furthermore, the use of magnetizing inductance guarantees zero voltage switching for all switches. Matlab/Simulink was used to simulate the suggested converter. The proposed converter is proven to offer a wide load variation up to 36% of the full load, with 400V input and 2.5 kV/2.77 A output based on the simulation results.
