This paper presents a 5-level multilevel inverter for low power applications that not exceeding 30W using the common LM350 voltage regulator IC. A microcontroller with appropriate program is used to control on the biasing resistance of the IC and H-bridge inverter in order to produce the quasi-sinewave looking waveform. Analysis of the output results are shown with levels of percentage harmonics. This new concept of multilevel inverter can be used for further study due to its simplicity and low in cost.
