“…Furthermore, during the last few years, a change of paradigm concerning the size of the grid-tied inverter has been observed [29,30]. Because of some limitations of big central inverters of power more than 100 kW, the present technology consists of the small size string or multi-string inverters which improve the MPPT of large PV groups of panel [14,31,32].…”

a b s t r a c tGrid-tied inverters are the key components of distributed generation system because of their function as an effective interface between renewable energy sources and utility. Recently, there has been an increasing interest in the use of transformerless inverter for low-voltage single-phase grid-tied photovoltaic (PV) system due to higher efficiency, lower cost, smaller size and weight when compared to the ones with transformer. However, the leakage current issues of transformerless inverter, which depends on the topology structure and modulation scheme, have to be addressed very carefully. This review focuses on the transformerless topologies, which are classified into three basic groups based on the decoupling method and leakage current characteristics. Different topologies under the three classes are presented, compared and evaluated based on leakage current, component ratings, advantages, and disadvantages. An examination of demand for the inverter, the utility grid, and the PV module are presented. A performance comparison in MATLAB/Simulink environment is done among different topologies. Also an analysis has been presented to select a better topology. Finally, based on the analysis and simulation results, a comparison table has been presented. Furthermore, some important experimental parameters have been summarized.

“…A simplified PID DC motor current control loop is shown in Figure 4. The gains (Kp & Ki) of the PI controller in the winding current control loop can be calculated using the winding resistance and inductance values and the desired current loop bandwidth (BW) in rad/s as shown in ( 6) and ( 7) [8].

In this study, in order to optimize the energy efficiency of a brushless DC motor (BLDC), a postintegration parameter calibration scheme is proposed and tested. The controller gains are calculated in the model using the motor parameters directly. A self-calibration algorithm is implemented, the change in parameters is logged and the resulting efficiency change is calculated and presented. At the end of the studies, a more effective system is obtained by checking the resistance and the inductance values.

“…Direct torque control (DTC) induction motor drive is becoming more popular day by day due to its fast dynamic response and robustness to the variation of the machine parameters without using the current controller [1][2][3][4][5][6]. Implementation of this control strategy is very simple and also coordinate transformation is not required.…”

-This paper aims to improve the performance of conventional direct torque control (DTC) drives proposed by Takahashi by extending the idea for 5-level inverter. Hybrid cascaded H-bridge topology is used to achieve inverter voltage vector composed of 5-level of voltage. Although DTC is very popular for its simplicity but it suffers from some disadvantages like-high torque ripple and uncontrollable switching frequency. To compensate these shortcomings conventional DTC strategy is modified for five levels voltage source inverter (VSI). Multilevel hysteresis controller for both flux and torque is used. Optimal voltage vector selection from precise lookup table utilizing 12 sector, 9 torque level and 4 flux level is proposed to improve DTC performance. These voltage references are produced utilizing a hybrid cascaded H-bridge multilevel inverter, where inverter each phase can be realized using multiple dc source. Fuel cells, car batteries or ultra-capacitor are normally the choice of required dc source. Simulation results shows that the DTC drive performance is considerably improved in terms of lower torque and flux ripple and less THD. These have been experimentally evaluated and compared with the basic DTC developed by Takahashi.
