A Simulation and experimental implementation of Four Switch Three phase inverter (FSTPI) fed Induction Motor drive is presented in this paper. Though the equations are pretty simple I can't figure out an appropriate way of modeling both electrical and mechanical characteristics (torque, inertia, friction etc). The model consists of PV array, DC link capacitor, DC-DC buck converter, three phase six-pulse inverter, AC inductive ﬁlter, transformer and a utility grid equivalent model.

[email protected] The IGBT inverter uses Pulse Width Modulation (PWM) at a 2 kHz carrier frequency. The power inverter is as currently available for HEVs use a dc-dc boost converter is to boost the battery voltage for a three phase inverter. The results show that in the partial shading conditions the three-level SVM inverter decreased THD in the presence or absence of DVR. Burt (M’95) currently holds a chair in Power Systems within the Institute for Energy and Environment at the University of Strathclyde. Finally a MATLAB/SIMULINK model for the SPWM is presented. The simulation of three phase five and seven level inverter fed induction motor model is done using Matlab/Simulink. The thesis provides insights into important modeling techniques to model the converter system, machine design, control and power stages and integration of the various sub systems to simulate the system level performance. Implementation and Design of Advanced DC/AC Inverter for Renewable Energy. The output of the block is the three-phase motor current references of the machine controlled by the average-value inverter. 10 Summary 133. PSCAD MODEL OF GRID-TIED PHOTOVOLTAIC SYSTEM The PSCAD model used in this paper is based on [2] and it mainly consists of PV array model, DC link capacitor, DC-DC converter, three phase inverter, AC ﬁlter, transformer. The optimal controller of the inverter helps to attenuate the harmonic components. 2 The inverter and a load model 33 4.
