“…There are some methods such as filtering using passive elements [28,29,34] and analytical approaches [30,35] addressed in the literature to reduce the harmonics produced by different devices, but all the methods have two defects. Firstly, they cannot completely eliminate the selected harmonics, and secondly, it is generally needed to apply some changes in the systems.…”

“…Moreover, they generate output voltage with lesser harmonics and thus reduces of filter requirement. In general, the conventional MLIs are categorized into diode‐clamped MLI, flying capacitor MLI, and cascade H‐bridge MLI (CHB‐MLI) topologies . Among these topologies, CHB‐MLIs have more popular because of their modular structures.…”

Summary This article presents a modified whale optimization (MWO) for harmonic mitigation in a three‐phase 11‐level hybrid cascaded multilevel inverter (HC‐MLI). The proposed MWO has improved rate of convergence as compared with conventional whale optimization (WO). This is achieved by improving the exploration‐exploitation feature of the conventional WO. Selective harmonic elimination–pulse width modulation technique is applied through MWO for generating the optimal switching angles of the HC‐MLI so as to eliminate the lower‐order harmonics such as 5th, 7th, 11th, and 13th from the output voltage. In the proposed MWO optimized HC‐MLI, capacitor voltage balance is made possible even at higher modulation indices using the available redundant switching states of HC‐MLI. The proposed work is useful where the HC‐MLI has to work at the low switching frequency and the conversion efficiency is of prime importance such as medium‐ and high‐power motor drives, static synchronous compensators, and active power filters. The performance of the proposed work is validated through simulation and experimentation on a 1.5‐kW prototype. The results obtained show that the MWO algorithm is more efficient and accurate than other reported algorithms such as genetic algorithm, particle swarm optimization, and WO in terms of performance, harmonic mitigation, and rate of convergence.

“…Similar to other types of inverters, essential defect of the PWM inverters is that they produce different orders of harmonics which have harmful effects on other devices [14, 15]. Using passive filters is a well‐known method to reduce harmonics [16–18]. Selected harmonic elimination (SHE) method is another technique to eliminate the selected harmonics which also results a reduction in total harmonic distortion (THD) [14–20].…”

In this study, a lithium (Li)‐ion battery equipped with an AC feature suitable for using in electric/hybrid vehicles is presented. The AC feature is implemented based on a proposed single‐phase symmetric pulse‐width modulation technique. Using the proposed Li‐ion battery including both DC and AC features (DC–AC power source) in electric/hybrid vehicles has some advantages such as less electric power consumption compared with a normal Li‐ion battery, no generated harmonics and the capability of choosing the AC voltage frequency. Simulated results obtained by performing in Proteus 6 environment validate the theoretical results presented in this study. An experimental prototype of the proposed DC–AC power source has been built. The experimental results not only verify the simulation and theoretical results but also show that 20% reduction in the electric power consumed by electric/hybrid vehicles is achieved using the proposed DC–AC power source.
