Abstract Electric polarization is a geometric phenomenon in solids and has close relationship to the symmetry of system. Here we propose mechanism dynamically induce manipulate electric by using an external light field. Specifically, show that application bicircular lights controls rotational system can generate polarization. To this end, use Floquet theory study subjected two-frequency drive. ...

The article deals with the issue of transition manufacturing enterprises and companies in oil industry to a new model interaction manufacturers electrical equipment, particular, electric drives. involves conclusion long-term contracts for use technical process support service. At same time, enterprise is not owner operated specific equipment. equipment manufacturer assumes obligations its suppl...

Legacy transformers are passive, bulky, becoming expensive, and take longer time to deliver. They cannot provide the power quality or control which today’s loads demand for proper functioning and the electric system needs for its survivability. Solid-state transformers have been promising technologies in recent years. EPRI is pursuing development of an innovative solution – the IUTTM (Intellige...

This paper presents an acceleration slip regulation strategy for distributed drive electric vehicles with two motors on the front axle. The tasks of the strategy include controlling the slip ratio to make full use of the road grip and controlling the yaw rate to eliminate the lateral movement due to the difference between motor torques. The rate of the slip ratio change can be controlled by con...

Due to the potential benefits resulting from the use of a phase order higher than three in transmission, some interest has also grown in the area of multi-phase machine. For machine drive applications, multi-phase system could potentially meet the demand for high power electric drive systems, which are both rugged and energy-efficient. High phase number drives possess several advantages over co...

Coarse and accurate power accounting methods for ship electric propulsion are observed and compared. For the purpose of analysis, the propulsion system has been separated into two units, namely the ship load and the motor drive. In the load model, variation of such factors like static and dynamic hull resistance and efficiency is explored while the supply characteristics, drive loading, propell...

This paper demonstrates the implementation of low cost switched reluctance motor (SRM) drive and application of RT lab as real time hardware-in-loop (HIL) controller. Split DC converter and positioning sensing arrangement is developed for 500W 8/6 pole SRM. Control part is implemented using Opal RT Lab technology. Application and optimistic characteristics of proposed low cost drive are describ...

induction motors are the most commonly used in the traction industries and electric vehicles, due to their low primary cost, low maintenance costs, and good performance. speed identification is needed for the induction motor drives. however, using of speed sensors in the induction motor drives is associated with problems such as, extra cost, reduced reliability, added mounting space, etc.. ther...
