Analysis of Non-Isolated Dual Output Tristate Converter for Low Voltage DC Bus

In this paper, a DC-DC Non-Isolated Single Input Dual Output (NI-SIDO) architecture with tri-state configuration is laid out, which is designed to provide both step-up and step-down outputs. The problem related to stability is mitigated by using tristate configuration in the presented NI-SIDO converter. The system is divided into three sub-systems having DC-DC tri-state boost converter and NI-SIDO converter as source converters and DC-DC buck converter acting as a load converter regulated using voltage loop control. The presented system performance and results are validated using MATLAB/SIMULINK software.
