hi
this is my problem dear reader could u kindly help me
Harmonics elimination PWM (HEPWM) is a method to create sinusoidal voltage by “killing” harmonics that are not required [1]. It is known to be superior to the traditional sinusoidal PWM because it gives better harmonics profile for a given switching frequency.
In this problem, you have to design a single phase inverter using the HEPWM switching strategy that can eliminate the first 7 non-zero harmonics. After obtaining the switching angles (using your numerical method of choice), you need to apply them to a single phase full bridge inverter with a power rating of 1kW (pure R load) and input voltage of 340VDC. Compare your results with the traditional SPWM that has “similar” switching performance. You need to simulate your inverter with PSPice to prove your result is correct.
thank u
