The present article proposes a three-phase resonant boost inverter (TPRBI) to feed a permanent magnet brushless DC (PMBLDC) motor at the requested torque with low ripples due to the sinusoidal current injected into the PMBLDC motor. PMBLDC motors have the highest torque-to-weight ratio compared to other motors and are the best choice for electric vehicle applications. Conventionally, these motors are driven by voltage source inverters (VSI) with trapezoidal current injection, introducing unwanted torque ripples. Moreover, due to the buck operation of VSI, an extra power conversion stage is required to elevate the battery voltage level to desired DC-link voltage. This extra stage increases the number of components used, complexity of control and decreases the efficiency and reliability of the overall system. TPRBI injects sinusoidal current in the PMBLDC motor in the proposed method, thus minimizing the torque ripples. The proposed inverter also has an inherent voltage boost characteristic, thus eliminating the extra power conversion stage. The single-stage conversion from DC to boosted sinusoidal AC enhances the system reliability and efficiency and minimizes the cost and weight of the system. A MATLAB/Simulink model is presented along with simulation results and mathematical validation. A comparative evaluation of the proposed system with the conventional VSI-fed PMBLDC motor is presented in terms of induced torque ripples.

Single-stage buck–boost inverters have attracted the attention of many researchers, due to their ability to increase/decrease the output voltage in one power conversion stage. One of the most important uses of these inverters is in photovoltaic applications, where the voltage of the solar panels varies in a wide range. In recent years, many new inverters have been proposed to improve the performance of existing structures. In this paper, the state of the art of these single-stage buck–boost inverters is discussed. The advantages and disadvantages of each structure are examined from different perspectives, such as the number of components, losses, and performance. Finally, in a general comparison, the properties of all structures are discussed and summarized in a table.

Multilevel rectifiers (MLRs) have been gaining popularity in a variety of applications due to their many advantages over two‐level rectifiers such as reduced voltage stress on power switches, much better harmonic profile of the input waveform, reduced dv/dt stress, possibility of fault tolerant operation, and so on. The use of higher number of semiconductor devices which are relatively more prone to faults plays a crucial role in determining the reliability of the system. In recent literature the performance analysis of the MLR in terms of cost, efficiency, reliability, and voltage stress has been majorly ignored. A five‐level rectifier topology with self‐voltage balancing capability has been implemented in this paper. The implemented topology has the capability to maintain the unity power factor (UPF) in all operating conditions. The in‐depth performance analysis in terms of reliability, efficiency and cost has been carried out to establish the suitability of the implemented topology for real‐time applications. In addition, the effect of various parameters on reliability has also been investigated. The MLR topology has been validated through experimentation. A qualitative and quantitative comparison of the proposed work with state‐of‐art has also been presented.
