Single Stage Multi Input DC-DC/AC Boost Converter with Sliding Mode Control

Objectives: This paper proposes a single stage conversion of multiple input dc to dc/ac output. This structure reduces multi stage conversion and eliminates the need of transformer. Methods/Statistical Analysis: The bidirectional switching port is used to reduce circuit complexity and for simple operation. The bidirectional circuit connects battery to load. The voltage is stepped up to high level using boost converter. The output obtained is pure ac/dc without the need of filter. The voltage can be regulated with the help of a battery which charges and discharges when required. The bidirectional circuit switching control is done by using sliding mode controller. Findings: The control of the converter is possible during the change in voltage from 40v to 50v. Novelty/Improvement: Implementing sliding mode control in simulation.
