<span lang="EN-US">The brushless DC motor (BLDC) has gained significant popularity in industrial settings due to its notable attributes such as low inertia, rapid response, high power density, exceptional dependability, and reputation for being conservation-free. Typically, these are equipped by a tight-switching PWM inverter, which results in significant switching losses. Consequently, the dissipation of switching loss necessitates the use of sizable heat sinks, resulting in an increase in both the physical dimensions and mass of the drive system. Numerous researchers have developed soft switching inverters with the aim of minimizing switching losses. The utilization of a soft-switching circuit may give rise to additional issues, including heightened voltage stress, incomplete pulse width modulation control, and intricate control scheme or implementation. The present study introduces a basic soft switch inverter design that is suitable for employment in BLDC drive systems powered by batteries. The inverter exhibits low loss for power switching and voltage stress is less on the main switches, while also featuring a straightforward control scheme that is easily implementable. Upon conducting analytical analysis, simulation results were presented by evaluating the theoretical analysis.</span>

This paper presents three high voltage gain DC-DC converters based on stacked input and output connection of nonisolated buck-boost converters with coupled inductor and voltage multiplier cells. Besides that, an empirical approach for the coupled inductor winding is proposed to show how to reduce the leakage inductance. In this way, the proposed converter achieves high voltage gain, low voltage, and current stress across the components without using an auxiliary clamp circuit, and they present a low component count. Besides that, this paper presents the evaluation of MPPT, modeling, and control of the converters. To validate the theoretical evaluations, three prototypes were built and evaluated experimentally, considering input power of 200 W, input voltage of 37.4 V, output voltage of 400 V, and switching frequency of 50 kHz. Finally, it should be noted that the maximum efficiency achieved is 97.53% at nominal input power.

Enhancement of organic solar cell efficiency by altering the zinc oxide photoanode nanostructure morphology

The current paper examines the effects of zinc oxide nanostructure configurations, as photoanode formations of organic solar cells, on the performance of power conversion. To this end, some experiments were conducted during which a near band edge emission red shift of ~0.11 eV from nanoparticles to vertically-oriented nanorods was observed. This bandgap narrowing promotes transferring of photo-excited electrons towards the conduction band of photoanode. A ~48% decrease in the deep level emission intensity revealed a smaller nonradiative waves emission due to lower level of crystal disorder. By using vertically-oriented zinc oxide nanorods as photoanodes, the photovoltaic efficiency of the organic solar cell improved considerably. The nanorod-structured photoanodes showed a 0.22 V rise in the open-circuit voltage, from 0.76 V to 0.98 V, and a 2.08 times increment in the overall conversion performance, compared to the zinc oxide nanoparticle-structured photoanodes. This superior performance is attributed to a greater chance of charge recombination and light-trapping in the cells, more efficient light absorption, and high level of crystallinity that grants easier electron mobility for vertically-oriented zinc oxide nanorods. Moreover, a smaller electron transfer impedance (0.85 ) was achieved due to better electrocatalytic action for oxygen reduction for vertical nanorods compared to the other two zinc oxide configurations (1.62  and 5.06 ). This boosted the cell performance by increasing the short-circuit current density (JSC). The fabricated solar cell may contribute to sustainable and environmentally-friendly electricity generation process through reducing the consumption of nonrenewable energy sources.
