In this paper, the authors deal with three-phase reverse voltage multilevel inverter with various PWM control strategies. Compared to conventional diode clamped, flying capacitor and cascaded H ...
PWM is a technique that is used to reduce the overall harmonic distortion (THD) in a load current. It uses a pulse wave in rectangular/square form that results in a variable average waveform value f(t), after its pulse width has been modulated. The time period for modulation is given by T. Therefore ...
