This paper proposes a control algorithm that controls a DC/DC converter within a capacitorless battery charger for Electric Vehicles (EVs). The charger is composed of an AC/DC converter connected to a three-phase DAB (Dual Active Bridge) DC/DC converter with no capacitor between those two. The proposed control adds an additional degree of liberty in order to deliver the reference charging or discharging power while mitigating the DC/DC converter's drawbacks, dealing with a varying voltage since there is no capacitor, operating in a wide range power spectrum, and controlling the transitional instants. The control algorithm's performance is verified using Matlab/Simulink, and the results are discussed.
