“…Knowing that the energy is held in the leaking inductor of the coupled inductor, it won't increase voltage stresses, yet incite huge switching losses of the switches in the converter. With a specific end goal to tackle these problematic issues, a few techniques have been proposed as listed in [6][7].…”

“…In [6], a resistor-capacitor-diode (R-C-D) snubber is utilized to mitigate switch voltage stresses, yet the energy caught in the leaking inductor is disseminated by the resistor, bringing about a lower conversion efficiency of the converter. A passive loss circuit [8] is adopted to recuperate the energy and lessen voltage spikes across switches; yet active switches are still functioning in hard switching mode.…”

The dependency of relying on switching power supplies is increasing and in more demand these days to present superior efficiency as it’s compared to conventional linear power supplies. The main target in any type of photovoltaic power system is to increase the efficiency rate of the PV arrays; and as a result power systems that depend on a set of PV arrays have a priority to track the maximum power point MPP to extract the ultimate maximum power from the set of arrays. One of their important characteristics is the ability to provide step-up in the form of Boost converters, step-down in the form of buck converters, and utilized in the sense of inverting. In this research paper we will delineate a sector of the various sort of switching regulators used in dc-dc conversion especially the boost converter. In addition a review of the control techniques for these converters were touched based.

“…A voltage source with a series connected inductor based isolated step‐up converter is suitable because of low current ripples. Active clamp and passive clamp have their corresponding disadvantages like power loss in residual current device snubber and active clamp with four switch topologies suffer from achieving high efficiency and cost [6–14]. The different topologies of the isolated converter, i.e.…”

“…However, since the energy is trapped in the leakage inductor of the coupled inductor, it will not only increase voltage stresses, but induce significant switching losses of the switches in the converter. In order to solve these problems, several methods have been proposed [23][24][25]. In [23], a resistor-capacitor-diode (R-C-D) snubber is used to alleviate switch voltage stresses, but the energy trapped in the leakage inductor is dissipated by the resistor, resulting in a lower conversion efficiency of the converter.…”

This paper presents a power system using a high step-up converter for dc load applications. The high step-up converter adopts a boost converter with interleaved mode and a coupled inductor to raise its powering ability and increase its step-up voltage ratio, respectively. In order to increase conversion efficiency, an active clamp circuit is introduced into the proposed one to provide soft-switching features to reduce switching losses. Moreover, switches in the converter and active clamp circuit are integrated with a synchronous switching technique to reduce circuit complexity and component counts, resulting in a lower cost and smaller volume. A perturb and observe method is adopted to extract the maximum power from photovoltaic (PV) arrays. Furthermore, a microchip associated with PWM IC is used to implement maximum power point tracking operation, voltage regulation and power management. Finally, a prototype PV power system with 400 V/6 A has been implemented for verifying the feasibility of the proposed PV power system. It is shown to be suitable for PV energy conversion applications when the duty ratios of switches in the dc/dc converter are less than 0.5.
