This topology was first proposed in 1981. They are also known as neutral point inverters. In 1992 a lot of research work was published on Diode Clamped Multilevel Inverters.
They have their fair share of advantages and disadvantages tied to them but then again, our firm faith in scientists and researchers has kept us calmly waiting for the better version of what we see today.
A 3-Level Diode Clamped Multilevel Inverter’s circuitry is shown above. If I try to define the initial target of this inverter, then it would be as simple as converting the DC voltage, which may come through any source even natural resources, into the capacitor voltage.
