Development and Study of 15 Level Multilevel Inverter for AC Distribution System in High Frequency Application
Keywords:multilevel inverter, diode, THD
For high-frequency AC power distribution systems, this study introduces a new multilevel inverter topology. Compared to other existing multilevel inverter, the suggested technology produces a staircase waveform with a higher number of output voltage levels with higher frequency. In the proposed system, the total number of switches and sources that used are extremely low. The harmonic content of the output voltage waveform is reduced as the number of levels increases. The type of multilevel inverter used in this paper is a cascaded multilevel inverter. To maximize the number of voltage levels, H-bridge configuration is proposed with three asymmetrical voltage sources as input with three diodes for construction. The output of the proposed topology can generate 15-level high-frequency voltage waveforms.
