“…Quantisation of the rate of change of active and reactive powers is carried out by taking the average of the (9) in kth sector with k − 1 (π/6) to k(π/6) as limits. The average rate of change of active power (Ṗ avg ) and reactive power (Q avg ) during this period can be written as ṗ 0 = 1.5 L e 2 and q = ωp (12) From (11), it is observed that x p k, n and x q k, n are independent of circuit parameters and hence their values are computed, which can then be applied to any voltage source converter topology as shown in Fig. 1.…”

“…In [8], a new switching table based on virtual flux is introduced and lesser THD in line current is achieved as compared to classical DPC. In literature [9][10][11][12][13], variants of switching tables for AFEs are discussed to enhance the performance but their formation methodology is not either discussed or properly presented. In [14], fuzzy logic-based switching state selection technique is presented to overcome the drawbacks of classical DPC technique.…”

Switching Table-based Direct Power Control (ST-DPC) is one of the most widely used techniques in Active Front-End (AFE) rectifiers. Proper control of switching states of the power converter is essential to obtain better power quality performance and quicker response to the load demand. In the classical ST-DPC techniques such as Virtual Flux with Noguchi's Table-based DPC (VF-NT-DPC) and Virtual Flux with Improved Table-based DPC (VF-IT-DPC) etc., these switching states are decided based on a predefined static switching table. Hence, they have poor power quality and dynamic performance with load variations. In this research work, in-depth mathematical analysis is carried out based on the quantised values of 'the rate of change of active and reactive powers' and an algorithm is introduced for AFEs. Since, the proposed algorithm is considering the quantised values of 'the rate of change of active and reactive powers', which is dynamic in nature; therefore, it has reduced THD, lesser power ripple, and quicker response than classical ST-DPC techniques. To show the superiority of the Algorithm based DPC (A-DPC) technique experimental work is carried out and the power quality performance of the proposed A-DPC is compared with conventional ST-DPC techniques VF-NT-DPC and VF-IT-DPC.

“…This control technique is vastly influenced by DTC, which is used for the control of induction motor. Further modified lookup tables are used for better power quality performance 2 . Depending upon the magnitude of errors of the power control loop, different switching tables are employed to limit the switching loss as well as to improve dynamic performance 3 .…”

Direct power control (DPC) technique for the control of ac-dc converters projects many advantages over conventional techniques. Even after the advent of upgraded DPC techniques, the conventional switching table-based DPC is preferred where a simple control structure with less computational burden is the design requirement. During the real-time implementation of any ac-dc converter or vice versa, the PWM signal for the converter/inverter operation is

“…There are many types of PWM rectifier control strategy, including direct power control strategy, its superiority is fast track power, power factor is high, the structure and the algorithm is simple, fast dynamic response [10], [11]. Generally, there are two types of DPC technique: voltage based DPC (VDPC) and virtual flux based DPC (VF DPC) [12], [13]. This paper puts forward a kind of three-phase PWM rectifier direct power control strategy which is based on virtual flux control.…”

The purpose of this paper is to develop a robust sensorless control based on the sliding-mode observer applied to a doubly fed induction motor associated with two three-level NPC-type voltage inverters fed by PWM rectifier. In this context, the authors propose in the first part, and after the presentation of the model of three-level NPC-type voltage inverters, this type of inverter has several advantages over the standard two-level inverter, such as a greater number of levels in the output waveforms, give less harmonic distortion in voltage and current waveforms and lower switching frequencies. They also present the control strategy of three-phase pulse width modulation rectifier. They propose the virtual flux-based direct power control (DPC_VF) with vector modulation (SVM). This method is applied for the enhancement of network power quality by compensation of harmonic currents produced by a non-linear load, and good regulation of DC-bus voltage. The second part of the paper is dedicated to the presentation of the robust observer for sensorless speed control of doubly fed induction motor (DFIM), based on the sliding mode. Simulation results of this proposed system were analyzed using MATLAB environment.
