“…Furthermore, zero voltage switching can be crucial to reduce size and cost. Also, the operation of high frequency gives small size and cost for magnetic components [18]. Although the full-bridge topology requires more switches, it reduces voltage and current stress [18].…”

“…The auxiliary Journal of Power and Energy Engineering circuit is preferred for push pull converter to reduce the voltage stress on the power switches [20], and the energy stored in a leakage inductance of the transformer can be safely removed. The disadvantage of push pull converter is challenging a problem that the switches have to withstand double the input voltage peak, this causes increase in conduction power losses [18].…”

“…Also, the operation of high frequency gives small size and cost for magnetic components [18]. Although the full-bridge topology requires more switches, it reduces voltage and current stress [18]. Full wave rectifier topology with a centred tapped secondary winding and two diodes are used to maximize the efficiency [22], smaller size and lower cost devices, and to make sure lowest voltage drop across the diodes.…”

“…The topology of push-pull converter is introduced by Yao Wang [18] to face the requirements of PV systems, as shown in Figure 5 and Figure 6, the first circuit is fed by voltage mode and the second by current mode. The advantages and disadvantages are summarised below for both circuits, the advantage in both modes of push-pull converter, it is clear has fewer elements in current path which reduces conduction losses [19].…”

DC-DC boost power converters play an important role in solar power systems; they step up the input voltage of a solar array for a given set of conditions. This paper presents an overview of the variance boost converter topologies. Each boost converter is evaluated on its capability to operate efficient, size, and cost of implementation. Conventional boost converter and interleaved boost converter are widely used topologies in photovoltaic systems reported; however, they have negative sides of varied efficiency level under changed weather conditions. Therefore, this paper proposes, interleaved boost converter with novel switch adaptive control, to maximise efficiency of standalone photovoltaic system under change of solar power levels, due to illadation condition.

Summary The use of photovoltaic (PV) systems has increased in recent years due to the high demand for clean energy sources. PV systems can utilize abundant and free energy from the sun, which is a substantial advantage. However, compared with other renewable technologies, the PV system still faces major obstacles such as high cost and low efficiency. In addition, fluctuating incident energy from the sun creates harmonics in the generated power that might lead to undesirable system performance. Total harmonic distortion (THD) is the ratio of distorted power to the main power of the signal, and is most commonly used to indicate the amount of signal distortion. THD has become a serious concern as more PV systems are integrated into grid systems. Previous research and reviews have attempted to reduce THD and its effect, but unfortunately focused on reducing THD at individual parts of the PV system. For the first time, this study holistically and systematically reviews the advances in THD reduction techniques for the entire PV system. The causes of harmonics, current solutions, and research gaps for further investigation are described in detail. Moreover, the current THD reduction techniques used in each stage of the PV system are compared, including their main benefits and drawbacks. Finally, this study recommends the use of adaptive filters as a possible solution for THD reduction because these filters have effectively reduced noise and disturbance in other systems.

Standalone power systems are becoming a suitable way of supplying telecommunications equipment, since they are being located in remote areas, which seems to be its nowadays and future trend location. Power electronics interfaces play an important role in these systems, because they are responsible for meeting load supply requirements. Photovoltaic (PV) generators are nonlinear sources, and behave mainly as DC current sources. As most telecommunications equipments operate from a DC supply voltage, the ideal power electronics interface to be used is a dc-dc converter. A literature survey showed that typical voltage source DC-DC converters are applied to photovoltaic generators, without many modifications. On the contrary, this paper presents a different DC-DC converter based on its current-source behaviour of a photovoltaic generator. © 2009 IEEE
