Abstract: Interconnection and Damping Assignment (IDA)-Passivity Based Control (PBC) is a promising control method for power converters which can guarantee the large-signal stability of complex modular Microgrids (MG). Passivity can be propagated between passive sub-systems by using the Port Controlled Hamiltonian (PCH) formalism and preserving the natural electrical ports interface for controlled systems. However, the solution based on this approach may cause the apparition of a singular region, leading to certain undesired behaviors. This paper proposes a new control strategy for a boost converter based on IDA-PBC technique, removing the singularities and preserving the closed-loop form used for the proof of passivity. A modified way of computing current reference is introduced and characterized. Experimental validation of the proposed controller is performed using a 3 kW experimental bench with voltage step-up from 200 V to 300 V. The performance of the controller is evaluated in a simulated DC-MG application and compared with a conventional controller. This work evaluates the robustness and dynamics of the proposed controller under variation of the model's parameters. [ABSTRACT FROM AUTHOR]
