Technological developments continue to increase, it is seen more and other electronic equipment used in day-to-day use, one of them in the field of electrical energy conversion, ie inverter. Inverter voltage variable power tool that can convert DC power into AC power. There are many studies done in order to get the output voltage of the inverter is a sinusoidal wave. However, the new technique in UNTAN strict academics has not been realized in the form of a real inverter device. Harmonic elimination technique is signal processing technique to get inverter pattern switch to get maximum output of sinusodal THD wave and minimum value. With combination of control signal generating circuit and AT89S52 LC microcontroller filter, the output inverter is expected to have sinusoidal wave. From the test results that have Has been done, harmonic elimination techniques can be used to obtain a sinusoidal voltage with total harmonic distortion is 9.1%.
