Dual channel DC-DC converter in continuous conduction mode

The paper presents the CCM (continuous conduction mode) operation of the dual channel resonant DC-DC step down (buck) converter. However, as a result of certain limitations, sometimes the converter cannot be operated in CCM at all. The paper presents the mathematical analysis of CCM operation, explores the basic relations between input, output and control variables for the more general asymmetric operation and gives simplified solutions for symmetric operation. To verify the theory, simulation results are also presented together with a comparison between some relevant numeric values from calculations and simulations. Finally, the advantages and drawbacks of CCM operation are summarized.
