A novel low-stress high-efficiency step-up DC-DC converter

The paper introduces a novel boost topology exhibiting comparable efficiency but lower semiconductor voltage stresses compared to the classical boost converter. Operation of the converter in continuous conduction mode (CCM) is similar to that of the classical hard-switched PWM converter, except for the fact that a resonant interval is introduced in the first topological state. After all design equations are derived, the theoretical aspects are verified against the simulations and finally the experiments accurately confirmed the feasibility of the new proposed architecture.
