Abstract

This paper proposes a simple, hardware-efficient digital pulse width modulator for a 4SBB that enables operation in Buck, Boost, and Buck+Boost modes, achieving smooth transitions between the different modes. The proposed modulator is simulated using Simulink and experimentally demonstrated using a 500 W 4SBB converter with 24 V input voltage and 12–36 V output voltage range.
Keywords: four switch non-inverting Buck-Boost; Buck+Boost mode; smooth transition four switch non-inverting Buck-Boost; Buck+Boost mode; smooth transition
