“…The effectiveness of the Z-Source VFDs is proven by no overshoot, no undershoot and zero steady-state error of the speed response. It is also seen in Figure 6 and Figure 7 that the speed response and the harmonic distortion of the reduced switch three phase Z-source VFD based IM drive It is found that the performance of the reduced switch three phase Z-source VFD based drive is much close to that of the traditional six switches three phase VFD [14]. The analysis and simulation results show that this VFD can dramatically reduce the complexity of the control algorithms and cost.…”

A cost-effective component minimized embedded controlled Z-source inverter for induction motor drive is presented. The proposed topology combines the advantages of a traditional four-switch three-phase inverter with the advantages of the z impedance network (two inductors in series and two X connected capacitors). This new topology, besides the self-boost property, has low switch count and it can operate as a buck-boost inverter. As a result, the new embedded controlled reduced switch Z-source inverter system provides ride through capability during voltage sags, reduces line harmonics, improves power factor, reliability and extends output voltage range. Analysis, simulation and experiment result will be presented to demonstrate these new features.

“…Literatures [14][15][16][17] concentrated on different control strategies for FSTP induction motors (IMs). In [18][19][20][21], the researchers focused on the applications of FSTP topologies in brushless DC (BLDC) [18,21] and DC motors [19,20], however, the machines mentioned above are not usually applied in wind energy conversion systems.…”

This paper investigates the performance of a fault-tolerant four-switch three-phase (FSTP) grid-side converter (GSC) in a doubly-fed induction generator-based wind turbine (DFIG-WT). The space vector pulse width modulation (SVPWM) technique is simplified and unified duty ratios are used for controlling the FSTP GSC. Steady DC-bus voltage, sinusoidal three-phase grid currents and unity power factor are obtained. In addition, the balance of capacitor voltages is accomplished based on the analysis of current flows at the midpoint of DC bus in different operational modes. Besides, external disturbances such as fluctuating wind speed and grid voltage sag are considered to test its fault-tolerant ability. Furthermore, the effects of fluctuating wind speed on the performance of DFIG-WT system are explained according to an approximate expression of the turbine torque. The performance of the proposed FSTP GSC is simulated in Matlab/Simulink 2016a based on a detailed 1.5 MW DFIG-WT Simulink model. Experiments are carried out on a 2 kW platform by using a discrete signal processor (DSP) TMS320F28335 controller to validate the reliability of DFIG-WT for the cases with step change of the stator active power and grid voltage sag, respectively.

“…Sinusoidal pulse with modulation technique is very famous technique for voltage source inverter because it is simple in implementation with low output harmonic contents [1,[9][10]. Analysis of six switches based three phase inverter and four switches based three phase inverter with PWM and Sinusoidal PWM comparison shows unbalanced phase currents, speed variations and higher THD of four switch three phase inverter fed induction motor discussed in [14]. Speed control is achieved in inverter driven induction motor by means of variable frequency.…”

This paper presents real time implementation of DSP based Sine PWM control algorithm for 3 phase 4-leg IGBT voltage source inverter. This method is useful to control the speed of Voltage source Inverter fed Induction motor drive. The pulses were generated using DSP controller through MATLAB Simulink-Code Composer Studio environment and that triggers the inverter. Results of input and output of the inverter were captured using Digital Storage Oscilloscope. Simulation study was carried out using PSpice and results verified.
