“…Therefore, the mechanical non-linear differential equations (67) to (70), with the magnetic non-linear differential-algebraic equations (66), describe the generalized non-linear dynamic model of squirrel cage induction machine. Because of non-linearity of the model, the advantage numerical solution methods must be used.…”

“…But the Space Vector Modulation SVM has been proved to be the most favourable pulse-width modulation schemes, thanks to its major advantages such as more efficient and high DC link voltage utilization, lower output voltage harmonic distortion, less switching and conduction losses, wide linear modulation range, more output voltage magnitude and its simple digital implementation. Several works were done on the SVM PWM firstly for three legs two level inverters, later on three legs multilevel inverters of many topologies [11], [43][44][45][46], [56][57], [65][66][67][68]. For four legs inverters there were till now four families of algorithms, the first is based on the αβγ coordinates, the second is based on the abc coordinates, the third uses only the values and polarities of the natural voltages and the fourth is using a simplification of the two first families.…”

Recently, for multilevel inverters, the various PWM performances can be properly controlled by an offset controller in the carrier based PWM modulator. It has shown a generalised algorithm for realizing a discontinuous PWM technique for defined common mode. For applications with variable load power factor, reduction of switching losses can be improved if common mode is properly adjusted to avoid commutation instants at high current amplitudes. In the paper, the problem, how to design a common mode in DPWM for variable load power factor will be investigated. A novel carrier PWM algorithm capable of offset control will be presented. The advantage is simple and flexible algorithm. This algorithm will be utilized in designing an optimized discontinuous PWM for variable load power factor. The method is mathematically formulated and demonstrated by simulation results.
