“…The presented structure of a five-level inverter can be used to construct resonant inverters. 28 The resonant inverters are particular converters operated with high-frequency values, generally superior to 1 kHz, to produce a high-frequency output voltage and current. Resonant inverter is characterized by high efficiency, high-power factor mode, and low harmonic currents.…”

This paper presents the implementation of selective harmonic elimination (SHE) in a five-level inverter structure using artificial neural networks (ANNs). SHE is an effective low-frequency modulation technique to eliminate selected harmonics and control multilevel converters. The use of ANN-SHE requires the calculation of the optimum values of switching angles via the solving system of nonlinear equations for the total harmonic distortion (THD) reduction, where the nonlinear equations are founded by the complex Fourier series analysis of the inverter output voltage. The procured switching angle values are directly implemented by a multilayer perceptron (MLP) algorithm without a lookup table. The ANN model is obtained by training the neural network (NN), taking the modulation index (M) as an input and approximating switching angles as an output. A thorough analysis was carried out to show the programming steps of the proposed ANN-based SHE using Matlab/ Simulink environment. A realized inverter prototype steered by the proposed ANN-based SHE was tested with various modulation indexes on a real-time mode using a digital signal processor (DSP) C2000 Delfino-TMS320F28379Dembedded board. A comparison between the simulation results and the experimental data is presented. The obtained results illustrate that the experimental results match the simulation closely, and the ANN model provides a fast and precise estimate of the switching angles for each value of the modulation index.

“…The brushless DC motor (BLDC) has gained significant popularity among various implementations due to its compact size, high power density, low at maintenance requirements, and exceptional reliability [1], all of which are crucial design considerations [2]. BLDC drives powered by batteries utilize a configuration of parallel and series batteries as their primary power source [3]. Typically, the BLDC motor is powered by a hard-switching PWM inverter, resulting in decreased inverter efficiency and the generation of heat that necessitates dissipation through a heat sink [4].…”

<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>

“…There is a several type of converters: AC to DC converters, DC to AC converters, AC to AC converters, and DC to DC converters. Also, the use of multilevel converters topologies in power circuits has many benefices, including the increase of the voltage level, the reduction of stress across static switches, the improvement of power factor with the reduction of power losses, the reduction of filter size [4][5][6][7][8][9]. DC to DC converters are widely used in many modern electronic systems.…”
