Indirect Sliding Mode Control of Proposed Non-Isolated Zeta-based Dual output converter

This article presents topology synthesis and control of a non-isolated dual output converter. The new integrated dual output converter is derived from a conventional Zeta converter. In a Dual output converter, the cross-coupling effect is unavoidable due to the presence of interacting dependable output voltage. Therefore, this article proposed an indirect sliding mode control (ISMC) to regulate both the output voltages. The Proposed ISMC employs a sliding surface function based on the inductor current error only and output voltage control can be achieved indirectly by inductor current. The inductor current reference is generated by PI controller and Voltage error. The performance of the proposed ISMC is verified in Matlab/ Simulink environment with the newly proposed Zeta-based dual output converter in terms of output voltage regulation ability under sudden changes in load resistance, input voltage and the output reference voltage.
