Objectives: Multiple Input Multiple Output dc-dc boost converters is used to interface diversified renewable energy sources to Asymmetric Cascaded H-Bridge Multilevel Inverter whose output voltages can be connected to the grid system. The compensators and/or controllers are required to provide the constant output voltages of the boost converter against disturbances along with desired time domain specifications. In this paper, two input two output dc-dc boost converter is developed to interface with seven level multilevel inverter. Methods/Statistical Analysis: One of the input sources is replaced by Photovoltaic panel and Incremental Conductance based Maximum Power Point Tracking Algorithm is developed to improve the efficiency of the system. Compensators are designed to maintain the constant output voltages of the converter against disturbances using transfer function model obtained from developed small signal model of the converter. The developed system is simulated using MATLAB /Simulink and the total harmonic distortion in the output voltage of the inverter is observed .The simulated closed loop output voltages of the dc-dc converter are validated by developing prototype model of the converter using AT 89C51 microcontroller. Findings: It is found that the two input two output dc-dc converter provides constant dc voltages to the asymmetric multilevel inverter from the diversified energy sources with improved time domain specifications using compensators. Application/Improvements: The designed system is having the applications in renewable power system, aerospace power systems and hybrid energy vehicle.
