Design of a New Single Phase 7-Level Reduced Switches Count Multilevel Inverter Topology

2. Proposed Topology

Proposed topology structure is shown in the figure. The proposed topology have simple configuration of eight switch and three voltage source (Thiyagarajan et al., 2019). Here voltage source have same dc link voltage so proposed topology is the symmetrical MLI topology. The maximum voltage generated across the load is three times the magnitude of voltage source. This is the extendable topology. With this topology we can obtain higher level output just adding the switches to main configuration part. In this topology the witch is IGBT. The switching scheme is shown in table 1. At any level only four switch is ON at a time for voltage level generation.
