“…It can be used for high voltage, high current, and high power applications in different industrial purposes. In addition, IBC has many attractive features such as: (i) minimal input current ripples; (ii) boosting the output voltage to higher levels; (iii) reducing the thermal stresses on the devices; (iv) lower current stress on the power switches and inductance hence; reducing the passive components size; (v) higher output power and efficiency; and (vi) higher power density [34][35][36][37][38][39].…”

The partially shaded photovoltaic (PSPV) condition reduces the generated power and contributes to hot spot problems that may lead to breakdown of shaded modules. PSPV generates multiple peak, one global one and many other local peaks. Many efficient, accurate and reliable maximum power point tracker (MPPT) techniques are used to track the global peak instead of local peaks. The proposed technique is not limited to global peak tracking, but rather it is capable of tracking the sum of all peaks of the PV arrays using an interleaved boost converter (IBC). The proposed converter has been compared with the state of the art conventional control method that uses a conventional boost converter (CBC). The converters used in the two PSPV systems are interfaced with electric utility using a three-phase inverter. The simulation findings prove superiority of the PSPV with IBC compared to the one using CBC in terms of power quality, reliability, mismatch power loss, DC-link voltage stability, efficiency and flexibility. Also, IBC alleviates partial shading effects and extracts higher power compared to the one using CBC. The results have shown a remarkable increase in output generated power of a PSPV system for the three presented scenarios of partial shading by 61.6%, 30.3% and 13%, respectively, when CBC is replaced by IBC.

“…Boost converter or step-up converter is used to convert a certain dc level voltage to a higher level dc voltage with a few amount of ac ripples (quasi-dc voltage) [1], [2]. In power conversion, particularly renewable energy, the boost converter is an important device as power electronics interface to provide a regulated output voltage to meet the load requirements because, generally, renewable energy sources have quite low and unregulated output voltage [3], [4]. As a switch mode power supply (SMPS), boost converter operation based on switching principle driven by pulse width modulation (PWM) with a constant frequency.…”

Interleaved boost converter gives good conversion efficiency due to its zero-current switching capability when operating in discontinuous conduction mode while keeping its input-output ripple current low. However, operating this kind of converter at interleaved operation for all the time gives poor efficiency under light-load condition. In this paper, an automatic operation region selector switch based on detection of the continuous or discontinuous current mode is proposed. With this switch, during the light-load condition, only one converter is activated, while during full-load condition both converters will be activated. The simulation results using LTspice software show that the proposed boost converter has a better efficiency compared to the conventional boost converter with efficiency range of 84.6 % to 95.32 % under various load conditions.

“…Hence, a snubber is introduced into the configuration for switch damage prevention. Over recent years, there have been a number of interleaved boost converters published in the literature [14][15][16][17]. The configurations of interleaved boost converters not only have the same advantages as conventional counterparts, but also lower the current stress in inductors and power switches using an interleaving mechanism, and suppress the input current ripple.…”

“…They cannot be applied to high output voltage operation, due to the fact that they provide the same voltage gain as a boost converter. In contrast, the interleaved boost converters, as presented in [18][19][20], have a high voltage gain advantage over those in [14][15][16][17] using capacitor of voltage doublers, and the voltage stress across power switches are lowered accordingly. Yet they are unable to boost the output voltage of fuel cells to a high voltage level due to an inadequate voltage gain.…”

This paper presents an interleaved inductor-coupled converter for a fuel cell. It is designed to boost a low input voltage from a fuel cell to a specified voltage level for DC load or high voltage DC link, thus providing a high-voltage conversion ratio. The presented converter mainly involves coupled inductors and capacitor of voltage doublers for boosting purposes, but the voltage ratings of the involved power switches and diodes, in particular, remain unaffected as the output voltage is boosted. Using an interleaving trigger mechanism, this circuit configuration can not only suppress the input current ripple, but also reduce the current ratings of power switches. In simple terms, it is a low-cost but high-voltage gain converter due to a smaller number of required components and the lower current and voltage ratings of power switches. The operation principles and design steps are detailed herein, and the performance simulations are experimentally validated at the end of the work.
