Switching is very important in energy conversion systems. The conversion process requires a good and reliable method. This research identifies methods or techniques for pulse width modulation. This technique proposes a new model of modulation technique, namely by combining level shifted modulation techniques, and adjusting the frequency in such a way that it produces a signal that suits the inverter's needs. The inverter tested in this research is an inverter with a bridge model configuration. The proposed research and methods were verified using MATLAB and Simulink software. The results obtained are the ratio of total harmonic distortion (THD) are 25.07%, 76, 66% and 9.183%, respectively
