The proposed method analysis the effective utilization of dc-link voltage for a Multi-Level Converter by controlling the sequential operation of switching devices as per the load requirement. Here a different switching pattern is followed, where the number of switching devices are switched ON depending on the value of input voltage needed for the inverter, thereby unnecessary switching ON of all devices are avoided. Initial DC needed voltage is generated from renewable voltage source. The proposal also quotes on various application of theses switching pattern in the field of renewable energy and voltage backup systems where voltage generated is utilized with minimal switching losses. This Varied DC link voltage method by Selective Switch Count (SSC) is used in Voltage Source Inverter. Simulation using MATLAB is used to validate the proposed SSC method feasibility.
