Multilevel Inverters with Imbricated Switching Cells, PWM and DPWM-Controlled

摘要

Multilevel voltage inverters with imbricated switching cells are destined to high and very high-power applications. These structures led to the normalization of the voltage distribution when the semiconductor devices are blocked and to the improvement of the total factor of harmonic distortions as compared to the classic inverter structures. Static power converters for high voltages generally need on-off switches (semiconductor devices) that can function under these voltages. If these switches are not available, different converter topologies must be developed, where only a voltage fraction is applied to each switch [1].
