Abstract

This paper proposes a new controller for power regulation in dual active bridge (DAB) DC−DC converter based on a new scheme that tracks minimum RMS current to ensure minimum losses. The proposed controller is based on an implementation of perturb and observe (P&O) tracking method that enables minimum current point tracking (MCPT) at any desired level of active power transfer and DC voltage ratio. The P&O is embedded in a closed loop control scheme which simultaneously regulates active power in DAB converter. The non-linear I-V characteristic of DAB presents the basis for this proposed controller and the rationale of using P&O algorithm. The proposed controller does not require complex non-linear converter modelling and is not circuit parameter dependent. Design procedure of the proposed controller is presented, and extensive simulation is carried out using MATLAB/Simulink to validate effectiveness of the proposed MCPT closed loop controller. An experimental prototype also substantiates the results achieved.
