Soft-switching three-level inverter

[1] The topology was developed in 2009 at HTWG Konstanz (Constance University of Applied Sciences).

Their construction typically makes use of power transistors and diodes.

To improve their efficiency, high-power inverters (from about 10 kW) frequently make use of a technique referred to as a three-level design (three-level inverter).

[4] This base design is supplemented by a snubber circuit consisting of a few passive components.

Furthermore, because the snubber circuit functions, in principle, without losses, the conversion efficiency of the inverter remains high even for high values of the switching frequency.
