Abstract—
It is generally accepted that interleaving techniques are efficient at reducing the input/output ripples and increasing the power output of boost converters operating in critical conduction mode.Pulse width modulation (PWM) is used to produce the switching pattern. But this technique causes large switching noise peaks at a multiple number of the carrierfrequency. This paper proposes Interleaved Boost DC-DC suitablefor renewable energy applications. The proposed converterutilizes delta-sigma modulation to control pulse generator. A thorough and effective analysis of the converter is carried out in order to achieve the system stability and to improve the dynamic performance. The output response obtained by this method is very much improved compared to the conventional PWM method of control. Simulation results are provided to illustrate the advantages of the proposed converter and controller scheme. All the advantages of interleaving, such as higher efficiency and reduced ripple for voltage/current, are also achieved in the proposed converter.
