Abstract
In this paper, a new multi-input-multi-output (MIMO) dc-dc converter with high step-up capability is proposed for wide power ranges. Also, in order to increase each output voltage, diode-capacitor (D-C) voltage multiplier (VM) stages are utilized in the proposed converter. The number of input stages, output stages, and VM stages are arbitrary and dependent to design conditions. At first, the general structure of proposed MIMO converter is presented. Then, in order to explain the converter operation, we walk through the design of a 1 kW four-input-two-output example, including loss and efficiency calculations. We validate the design with a prototype that matches efficiency calculations.
