Project Objectives

Reduce the Harmonics Loss in Pure Sine Wave Single Ø-Inverter and Reduce Its Cost

Project Implementation Method

The framework comprises of control circuit which is microcontroller circuit that utilization to create SPWM pulse. Then, the inverter full bridge circuit to give the result. LC filter was utilized to decrease harmonic, so it will create the sine wave signal. Finally, the signal forward to transformer to expand the voltage to 230v. The recreation model of unipolar SPWM inverter is partition into three sections which are control circuit, an inverter circuit and low pass filter circuit. The switching component use in this development is power MOSFET in light of the fact that it should be power commutated component with high-frequency switching. A low pass filter is working to decrease harmonics created by PMW. The circuit of low pass LC filter that needed at the result terminal of full bridge inverter. The worth utilized in the model for inductor and the capacitor.
