Inverter is an electronic device which is an important part to convert DC-AC energy. Increased use of renewable energy as a substitute for fossil energy that is running low encourages the increased performance of the inverter. Multilevel inverter offer many advantages for improving the performance of an inverter system. Diode Clamped Multilevel Inverter are explored with 7-level circuits that are analyzed and simulated specifically on the quality of the output ie the amount of harmony. The power switch control technique uses Anti-Phase SPWM with multicarrier. Further to maximize damping harmonics, LC filter is applied and researched. This research is using PSpice A / D Lite to simulate a system that worked. The results obtained harmonic attenuation reached 3.93% after LC filter.
