Abstract

In this paper a new current control method is proposed for the discontinuous conduction mode of boost converter. The proposed method using a current gain feedforward compensation adjusts a measured inductor current value and then, calculated an average current precisely in the discontinuous conduction mode as well as continuous conduction mode. By applying the proposed method, the current measurement error is significantly reduced to 2% regardless of the operating points. The proposed method is analyzed and its performance is investigated in simulation. To verify the feasibility of the proposed scheme, a 10kW 3-phase interleaved boost converter was built and experimental results are matched to the simulation results.
