“…By adjusting the phase shift between the carriers, the current at the input of the inverter can be manipulated. Various different modulation techniques were already investigated and presented in the literature [27]. For this study, the most promising modulation techniques are applied to the simulated drive train and investigated in detail.…”

E-mobility is an emerging means of transportation, mainly due to the environmental impact of petroleum-based fuel vehicles and oil prices’ peak. However, electric vehicles face several challenges by the nature of technology. Consequently, electric vehicles have a limited travel range and are extremely heavy. In this research, an investigation is carried out on different measures to reduce the DC-link capacitor size in the drive train of an electric vehicle. The investigation is based on software simulations. The DC-link capacitor must be dimensioned with regards to relevant points of operation, which are defined by the rotation speed and torque of the motor as well as the available DC-link voltage. This also includes the field-oriented control (FOC). In order to optimally operate a three-phase inverter in the electric drive train, a suitable type and sizing of the capacitor was studied based on mathematical equations and simulations. Two measures were examined in this study: firstly, an auxiliary passive notch filter introduced in the electric drive train circuit is explored. Based on this measure, an advanced modulation scheme exploiting the control of individual currents within segmented windings of the PMSM is investigated in detail. It was seen that saw-tooth carrier modulation used in the parallel three-phase inverter is found to reduce DC-link capacitor size in the electric drive train circuit by 70%.

“…The pulse-width-modulation technique is replaced with the space-vector-pulse-width-modulation (SVPWM). [4] It is the most excellent pulse-width-modulation-technique for a 3-Φ voltage-source-inverter as give less harmonics and good power factor [5].…”

This paper represents, reduced harmonics in the three phase three module inverter. If the module number increases the Total-harmonics-distraction (THD) value of the traction drive reduced. And the THD value is tremendously reduced by using controller with three phase three module inverter. Here Proportional Integral (PI) is used as a controller. The THD values for the three modules with controller and simulink results are placed below. The performance a characteristic of the traction drive is improved compared with and without controller. And the simulink results are placed below.
