Multi-Input Multi-Output High Step-Up DC-DC Converter with Low Voltage Stress on Semiconductors

Abstract

This article introduces a Multi-Input Multi-Output (MIMO) high step-up transformerless DC-DC circuit. Designed for a broad spectrum of applications, the proffered configuration facilitates the integration of multiple hybrid voltage sources to power diverse loads with varying voltage requirements. Simultaneous regulation of all output voltages across the output ports is achieved by tuning individual controlling parameters. To enhance the analysis, a careful investigation is conducted into the single-input, dual-output (SIDO) operation of the proffered circuit. To validate the theoretical findings, a mock-up demonstrating the SIDO operation of the circuit is implemented for a 20V input voltage, producing output voltages of 100V and 195V, with a total power output of 600W.
