| ABSTRACT |
Single Phase Cascaded Multilevel Inverter with SHEPWM switching technique offers good output voltage waveform. By using SHEPWM switching technique, the selected harmonic order can be eliminated and can contribute to the low Total Harmonic Distortion (THD) for the voltage output waveform. The field programmable gate array (FPGA) use to generated SHEWPM switching pulses for the cascaded multilevel inverter. This multilevel inverter can convert DC voltage to AC voltage. There have a lot of power source that could be use as a input voltage (DC) for this multilevel inverter such as wind and solar. Main reason using multilevel inverter because the energy from different renewable energy sources can be used simultaneously. The inverter produced 3 to 9 levels output waveform with various frequencies and different switching pattern. The output voltage is 240 AC and the inverter is capable of generating the selected level which can deliver a maximum 1500 Watt of power.
