Implementation of Equal Areas-PWM in Multilevel Inverters
This paper presents the implementation of the equal areas pulse width modulation (EA-PWM) method in multilevel inverters. According to EAPWM, the integrated area of the pulse must be equal with the integrated area of the reference sinus waveform during the corresponding interval. Matching the volt/second areas, one can derive algebraic mathematical equations to calculate the pulse’s firing and active time. The equal areas criteria are implemented for each level of the inverter. Extensive simulation has been carried out along with practical implementation which validates the simulation results. Two modulation cases of 7-level multilevel inverter using cascade topology were used. In order to formulate the equations in this paper an example of a 9-level multilevel inverter is used. It is assumed that the DC sources are equally valued.
