This paper presents a new pulse width modulator control method using the offset function to reduce switching loss in five-level Cascade inverter. The proposed technique is based on the offset function being 3rd harmonic voltage. The offset voltage will be added to the control voltages so that the voltage of phase which has absolute of load current largest move into top or bottom of the carriers. |
