Abstract
This paper proposes a simple but robust control method for the effective operation of the cascaded buck-boost converter using only one output voltage controller in combination with logic circuits. The converter has an input voltage range from 450V to 750V, providing an output voltage of 600V and up to 15ARMS output current. An analytical single-controller design approach shows stable and robust behavior throughout the whole input voltage range in both continuous conduction mode (CCM) and discontinuous conduction mode (DCM).
