Abstract This paper proposes a switching control strategy (SCS) for a bidirectional DC/DC converter. The aim of this strategy is managing the power that an ultra-capacitor (UC) has to deliver or absorb following a power reference required by the driving cycle ECE-15 of an electric vehicle (EV). For that purpose, the converter is modelled as a switched linear system. Based on hysteresis and logic switching, a switching rule is designed. Necessary and sufficient conditions for the existence of the switching rule are established. Simulation and experimental results of a 1 kW converter are shown to demonstrate the feasibility of this strategy.
