“…FW algorithms modify the direct current of PM motors; however, this action may be carried out in several ways, and each approach has its own advantages and drawbacks. The authors of [32,33] analyze the existing methods and provide a brief review and classification. In their work, they divide the techniques into feedback, feedforward, and mixed methods.…”

In recent decades the market share of electrical cars has increased significantly, which has paved the way for the development of automotive electronics. Some of the most important parts of modern electrical vehicles are motor drives, which are used in car training and mechanization. Electrical drives are used in powertrains for traction, in air conditioning systems to cool cars and their parts, in doors for opening/closing as well as window movements, etc. The most popular motor type in electrical vehicles is synchronous motors with permanent magnets, which are compact and provide high torque. However, these motors require the development of control systems for proper operation. This system has to have the capacity to implement several state-of-the-art techniques, which can fully utilize motor potential, increase its efficiency, and decrease battery usage. One of these techniques is field-weakening, which overcomes speed limitations due to a lack of supply voltage and increases the motor’s speed operation range. This paper discusses the most popular approaches to field-weakening, including a new method proposed by the author. It considers both the pros and cons of each approach and provides recommendations for their usage. After that, this manuscript demonstrates the experimental results of each field-weakening technique obtained in the same motor drive, compares their performance, and discusses their strengths and weaknesses. Finally, the experimental part demonstrates that the proposed field-weakening approach demonstrates similar dynamics in load transients but provides 10 times less load to the microcontroller.

A new grid driver of a high-side N-type switch tube is designed, which is easy to integrate. The circuit has the characteristics of low cost and fast speed and solves the problem of the unstable output voltage of a high-side switch tube when a low-side switch tube is not working in a traditional bootstrap circuit. The power supply voltage of the circuit is 30 V, including the voltage bias module, a high-level voltage shift circuit module, and a charge pump module. It can meet the driving requirements of a large size and high-side N-type switch tube. In this study, the 0.18 μm MGN process was used for design and simulation. The simulation results show that the grid driver has good driving ability.

“…In motor applications, this can be used to improve the performance of machines that are operated at a wide range of speeds. The benefits are related to field weakening [37,38], where the power and torque can be controlled depending on the operation speed. Such benefits have been studied by Cinti et al [34], who compared PM machines and HE machines, and showed the advantages of operating with a good efficiency at variable speeds.…”

Hybrid excitation is a technology that combines the advantages of field windings and permanent magnets for inducing magnetic flux. This article studies the benefits of hybrid excitation and provides an outlook on their possible applications, such as wind power generators and electric vehicle motors. Compared to permanent magnet-based machines, hybrid excitation gives a variable flux while still using the advantage of the permanent magnets for a portion of the flux. This article also looks into some different categories of machines developed for hybrid excitation. The categories are based on the reluctance circuit, the relative geometrical location of the field windings relative to the permanent magnets, or the placement of the excitation system.
