Abstract :

Inverter is a devices that functions to convert DC input voltage to AC. One technique for optimizing the inveter output is SPWM. In this final project, a single–phase SPWM inverter with bipolar SPWM switching is designed. This inverter has 1 phase H-Bridge spesifications, with IGBT components, resistors, warehouse and inductors where there are 4 MOSFETs that can be connected. By carrying out 3 test with different sources for a 244.44 volt DC source it produces 0,47 % harmonic, a variable DC source produces 54,81 % harmonics and for a PV sources 9,91 % harmonics. Of the three test, the largest harmonic value is by using a variable DC source. Large harmonic can affect the shape of the wave to be non-sine and the wave has lots of ripples. This simulation aims to facilitate the design of real inverter devices.
