This paper proposes a single-phase multi-level inverter controlledby a microcontroller providing the signal voltage waveform output of seven level. The model simulation program is given using Matlab/Simulink program to compare with the built prototype at rated load impedance 2 kW and the switching frequency of 50 Hz and 16 kHz. Test results case control the switching frequency 50 Hz at the results showed that the highest rating THDv 12.93% and THDi 13.34%. In case of controlling switching frequency 16kHz at rated found that THDv 40.03% and THDi 31.54% and the results compare is based on results from simulation., Which is considered acceptable.
