Highly Efficient and Compact Single Input Multiple Output DC-DC Converters

Novel dc-dc converters with a single input and multiple outputs has been proposed in this paper. The features of the proposed topology are (a) reduced part count leading to compact and lightweight circuit, (c) high voltage gain, (d) single input double output, (e) low ripple in the input as well as output side, and (f) a minimal number of active switches. Apart from this, the paper highlights the modifications of the proposed converter to incorporate the advantages of interleaving as well as generate two independently controllable output voltages. The method of generating two equal and opposite output voltages with the help of a single switch has also been proposed with the addition of minimal circuitry. Operating modes of the proposed converters have been explained followed by a detailed steady-state and the dynamic modeling. To verify the validity of the proposed converters, simulations has been carried out using Matlab-Simulink and experiments have been carried out through a hardware laboratory prototype, whose results are included in the subsequent sections of the paper.
