Abstrakty

EN

Cascaded Multi-level Inverter (CMLI) consists of H-bridge modules which can generally be divided into the one with the same DC bus voltage and another with different DC bus voltages. By using the same power devices as a standard seven-level 3H-bridge converter, the proposed converter operates with 15-level resolution, with separate DC voltage sources of voltage ratio 4:2:1. The total harmonic distortion (THD) and switching losses of the proposed hybrid cascaded converter among staircase, PWM and partial PWM control are compared with analysis and Saber simulation.

W niniejszym artykule przedstawiono trzy metody modulacji dla 15-poziomowego kaskadowego falownika hybrydowego. Dokonano porównania analitycznego i symulacyjnego metod przełączania schodkowego, modulacji PWM i częściowej PWM pod względem THD oraz strat łączeń. Analiza i symulacja wyników wykazują, że proponowane metody modulacji pozwalają na uzyskanie wysokiej jakości napięcia.
