This article introduces a novel Model-Based Control strategy for a bidirectional double-input DC-DC boost converter with three controllable switches. The converter is suitable for electric vehicles and distributed generation, as it can interface renewable energy sources and energy storage devices like supercapacitors or batteries. The algorithm computes the most efficient duty cycles for the switches by analyzing target conditions generated from the reference values of source currents, ensuring accurate and rapid response. Moreover, Discontinuous Conduction Mode is exploited. The superiority of the proposed method over a PI-based approach is demonstrated by experimental tests.

Abstract
This article introduces a novel Model-Based Control strategy for a bidirectional double-input DC-DC boost converter with three controllable switches. The converter is suitable for electric vehicles and distributed generation, as it can interface renewable energy sources and energy storage devices like supercapacitors or batteries. The algorithm computes the most efficient duty cycles for the switches by analyzing target conditions generated from the reference values of source currents, ensuring accurate and rapid response. Moreover, Discontinuous Conduction Mode is exploited. The superiority of the proposed method over a PI-based approach is demonstrated by experimental tests.
