Single Phase Cascaded Multilevel Inverter with Selective Harmonic Elimination Pulse Width Modulation (SHEPWM). 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. Light and compact design allows the product to be portable. The energy from different renewable energy sources can be used simultaneously. This product can produce up to 9 levels output waveform with various frequencies and different switching pattern. This, it gives a lot of potential for research and educational application. Capable of generating 240 AC with a maximum power of 1500 Watt.
