Abstract：In order to reduce the input inductor current stress of the basic quadratic Buck-Boost converter, a quadratic Buck-Boost converter based on switched inductance is proposed. The energy transmission process of the converter under L1-CCM/L2-CCM/ L3-CCM is analyzed in detail. It is pointed out that whether the inductance L1 and L2 are equal in this mode only affects the working mode of the converter; the relational expressions of the converter voltage gain, the input inductor current stress expression are derived. The CCM and DCM critical conditions and critical inductance values of the inductors L1, L2, and L3 are given. Compared with the basic quadratic Buck-Boost converter, the converter voltage gain is increased by two times, and the input inductance current stress is reduced by one time. The feasibility of the proposed circuit and the correctness of the theoretical analysis are verified by simulation and experiment.
