The 3‐level boost (3LB) converters have the characteristics of higher‐voltage conversion ratio and efficiency, lower inductor current ripples, output voltage ripples and voltage stresses on switches when compared with the conventional boost converters in continuous conduction mode (CCM). When implemented into an integrated circuit, the 3LB converter discontinuous conduction mode (DCM) operation cannot be avoided due to a smaller inductance. Its DCM operation analysis is deduced including CCM/DCM boundary, DCM voltage gain and DCM small signal transfer function. The deduced DCM operation theory is verified using MATLAB and Cadence, to obtain a feasible DCM closed‐loop controller design in future.
