Manfred W. Gekeler: Soft Switching Three Level Inverter (S3L Inverter)
Abstract
The S3L inverter is a novel circuit topology for three-level PWM inverters in the medium
and high power rünges. Soft switching is usedfor all comruutations, which therefore have
no switching losses on principle. The result is signfficantly lower power dissipation end
outstanding fficiency. There is also no need for an external du/dt filter.
