“…The three-level NPC inverter applies three output voltage levels +V dc /2, 0, −V dc /2 across the motor winding which reduces the harmonic distortion in the inverter output voltage and current waveforms. As the output voltage increases in small steps, dv/dt stress and inverter losses are less in the three-level inverter compared to the two-level inverter at a higher switching frequency (Raju et al , 2012; Ozturk et al , 2010; Shi et al , 2010; Shchur and Turkovskyi, 2020; Chuang and Ke, 2009; Chen and Fang, 2008).…”

Purpose The conventional two-level inverter suffers from harmonics, higher direct current (DC) link voltage requirement, higher dv/dt and heating of the rotor. This study aims to overcome by using a multilevel inverter for brushless DC (BLDC) drive. Design/methodology/approach This paper presents a comparative analysis of the conventional two-level and three-level multilevel inverter for electric vehicle (EV) application using BLDC drive. Findings A three-level Active Neutral Point Clamped Multilevel inverter (ANPCMLI) is proposed in this paper which provides DC link voltage control. Simulation studies of the multilevel inverter and BLDC motor is carried out in MATLAB. Originality/value The ANPCMLI fed BLDC simulation results shows that there is the significant reduction in the BLDC motor torque ripple, switching stress and harmonic distortion in the BLDC motor fed ANPCMLI compared to the conventional two-level inverter. A prototype of ANPCMLI fed BLDC drive along with field programmable gate array (FPGA) control is built and MATLAB simulation results are verified experimentally.

“…One of the main requirements for multi-mass control systems is also the requirement for the robustness of the synthesized system, i.e. the ability of the system to maintain the technical requirements imposed on it when the parameters of the control object and external influences change within certain limits [13,14].…”

“…Also we introduce vector of the parameter of uncertainty of external magnetic field model [23,24]. Then the problem of synthesis of systems of active shielding is associated with computation of such vector of the required parameters of systems of active shielding which assumes a minimum value from maximum value of the magnetic flux density at selected points of the shielding space [25][26][27][28][29]. However, in this case, it is necessary to simultaneously determine such a value of vector of the parameter uncertainty, at which the maximum value of the same magnetic flux density is maximum.…”
