What are the basic multilevel inverter topologies?

March 26, 2025 By Rakesh Kumar

A multilevel inverter (MLI) is a power electronic device designed to generate a stepped ac voltage level at its output by combining multiple lower-level dc voltages as inputs. This FAQ will cover the three basic MLI topologies: diode-clamped MLI, capacitor-clamped MLI, and cascaded H-Bridge MLI. Conventional two-level inverter and MLI A conventional two-level inverter (Figure […]
