With the rapid development of dc system, residual current in system has become an urgent problem to be solved. However, type B devices (RCD) for ac systems could not directly used systems. In voltage fluctuation generated by rectifier and circulating net currents line with different positive negative parameters would interfere detection RCD. this paper, experimental platform was built firstly. ...

Dynamic wireless charging enables moving equipment such as electric vehicles, robots to be charged in motion, and thus is a research hotspot. The applications practice, however, suffer from mutual inductance fluctuation due unavoidable environmental disturbances. In addition, the load also changes during operation, which makes problem more complicated. This paper analyzes impacts of equivalent ...

Acknowledgment First of all, I would like to thank my parents who raise me and support me to do further study in Norway. I appreciate the help from my supervisor Lars Einar Norum and Phd student Hamed Nademi. I benefit a lot from their meticulous attitude to study, abundant knowledge and minded guidance. I am very grateful that NTNU Department of Electric Power Engineering provides very good ha...

In this paper, we introduce transformations of deep rectifier networks, enabling the conversion of deep rectifier networks into shallow rectifier networks. We subsequently prove that any rectifier net of any depth can be represented by a maximum of a number of functions that can be realized by a shallow network with a single hidden layer. The transformations of both deep rectifier nets and deep...

High resolution (Doppler-resolved) measurement of Doppler-shifted ion absorption frequencies allows the determination of the electric field responsible for the shift. A new method based on velocity modulation laser spectroscopy is described for the nonperturbative measurement of the axial electric fields in glow discharges. The A ‘n, + X I&+ (4.0 ) band of NT has heen used as a probe of a He/N,...

This paper proposes the use of simulation techniques to solve specific problems encountered in the use of three phase rectifiers to control the switching of A.C. drives with an induction motor. The solution proposed in the paper is based on the PRACED simulator and is applicable to pulse rectifiers of A.C. electric drives. The PRACED simulator is shown to be especially useful in the design and ...
