The transient and steady state analysis of Modified Three Phase Multilevel Inverter (MMLI) for Photovoltaic (PV) system fed from single DC input is presented in this paper. The transient and Steady state conditions of modified three phase multilevel inverter are analyzed using Proportional Integral (PI) and Fuzzy Logic Controller (FLC) with change in irradiance level of PV panels. The three phase multilevel inverter  is designed with reduce number of power semiconductor switches, components, single DC input and effectively controlled by using Space Vector Pulse width Modulation technique (SVPWM).  The obtained results are validated using MATLAB/ Simulink.Finaly, semiconductor switches and componets utilization of MMLI is compared with other similar topologies.

In this research, has been a developed  modular approach  for investigation of the dynamic behavior and analysis the steady -state and transient cases  for a three-phase induction motor when it is fed with a balanced and unbalanced voltage , and analysis the  behavior of the Torque-Speed characteristics at various conditions. This analysis is done systematically by development two mathematically models. Where the first model is proposed   to simulate the dynamic behavior of the motor when supplying it at balanced and unbalanced voltage in Matlab/Simulink by using d-q axis theory in the reference frame. This model can investigate and described in details the behavior of the induction motor  parameters, and enables the researcher to calculate or investigate any variable for an induction machine  parameter ; (e.g. The  voltage, current, flux, speed and torque as a function of time) in both cases  transient and steady state , when the motor in operation state  [11-16].  The other model is proposed to simulate in the Microsoft Excel program, by using  the ratio between the conventions  of the electromagnetic torque equation(Tem)  and maximum torque equation (Tmax) . To study and analysis the behavior of the Torque-Speed characteristics for a 3-phase induction motor. Where this models study's by using Excel program's and Matlab / Simulink to simulation the effect of the various parameters on the dynamic behavior of the motor such as  inserting variable external resistance in series with rotor circuit , and when supplying the stator by variable voltage. These Mathematical models could be   used for a wide range of motors which has a various horse powers , which needing it in a scientific research and practical applications.

This paper presents the steady-state and transient behavior of a single-phase self-excited induction generator (SEIG) using a three-phase machine with one shunt and one series excitation capacitors for resistive and inductive loads. The generation scheme consists of one three-phase delta connected induction machine and two capacitors - one connected in parallel with one winding and the other in series with a single-phase load. The dynamic model of the system has been developed as a hybrid model considering the stator phase currents in abc reference frame and the rotor currents in stationary d-q axes reference frame as state variables. The simulated and experimental results are presented for different dynamic conditions such as initiation of self-excitation, load perturbation and short-circuit. The simulated results of the steady-state analysis have been compared with the transient and experimental results and a close agreement between them indicates the accuracy and effectiveness of the approach.
