Control of power flow in a resonant DC-DC buck and boost converter

The paper contains a detailed analysis of the steady-state operation of the dual channel resonant DC-DC step up/down converter. The limits of the real operation have been marked out and the regions of continuous conduction mode (CCM) and discontinuous conduction mode (DCM) have also been separated. Three kinds of power flow control methods are observed, but the application of a combined strategy is also possible.
