“…Control methods like synchronous reference frame theory (dq0 theory) [19], instantaneous power theory (pq/ α-β theory) [20], symmetrical component theory [21], [22], [23], Power balance theory (PBT), Artificial neural network (ANN) controller [24], Fuzzy logic controller [25] and Sliding Mode Control theory [26] were introduced during the past decade including in order to acquire the reference voltage and current values in UPQCs. Also, a suitable control technique must be used to generate the pulses required by the inverter and some of these control techniques are hysteresis control method, sinusoidal pulse width modulation (SPWM), space vector modulation, and dead-beat control method.…”

Mitigating power quality issues in distribution systems is of utmost importance to both electricity consumers and suppliers as it improves the distribution system's efficiency, reduces electricity costs, maintains continuous supply, and diminishes the requirement for frequent maintenance. Custom power devices were introduced to eliminate power quality issues like voltage sags, swells, transients, imbalances, and current harmonics arising in distribution systems. Unified power quality conditioner (UPQC) is one such frequently used custom power device that enhances the power quality of distribution systems. Various structural arrangements of UPQCs with improved performance capability were introduced within the last few decades. The main aim of this paper is to review the most frequently explored UPQC models in literature and to observe the impact of these UPQC structural configurations on their performance as well as that of the overall distribution system. Also, this study investigates the properties, applications, and control techniques used by these structural configurations of UPQCs to mitigate power quality issues.

“…However, due to presence of more number of capacitors, the surge current may appear at every cycle and leads to damage the switches. Switched inductor type concept is also having unique feature and can produce higher voltage [16], [17]. But the switching stress is higher at large duty ratio and increases the switching losses and degrades the efficiency.…”

<span lang="HR">Solar photovoltaic (PV) system becomes popular to generate the electricity in Asian region and helps to reduce the burden to utility. The power converter plays crucial role to interconnect with DC- grid. Traditional type power DC-DC converter can able to extract the maximum power from solar PV. However, most of the applications, it often fails to meet the voltage level of the DC bus and additional converter is required to boosting p the DC voltage. In order to overcome this drawback, this paper proposes a novel DC-DC converter to extract the maximum power from solar PV and helps to enhance the voltage level to meet the DC-bus. The PV and IV characteristics of practical solar PV cell and mathematical modelling have been done and implemented the same to proposed high gain converter. The maximum power point tracking (MPPT) algorithm and operation details are addressed and the detailed operation waveform of proposed high voltage gain DC-DC converter with mathematical evident is reported in this paper. The simulation study was carried out in the PSCAD/EMDTC software. From the measured results, it is investigated in further to validate the MPPT operation, gain values achievement and performance analysis of proposed converter. The corresponding explanations and results are presented in this article.</span>
