abstract: Electrically propelled ships gained popularity by the early 20th century, with the rapid development of submarines and mediumcapacity container ships, mainly using dc motors [1] Synchronous ac motors have since been employed for naval propulsion systems, but due to the restricted operation of the available power electronic devices at that time, these configurations were too expensive and unreliable, and they featured poor performance in terms of speed and torque control [2] Improvements in power electronics devices and drive control schemes as well as the development of high efficiency multiphase induction and synchronous motors have pushed the advancement of electric ship propulsion systems and applications [3] [7]

abstract: Modern electric drives are generally driven by voltage source inverters. With the aim of reducing size and losses, switching speed of modern power electronic devices is steadily increasing. At the same time, it can be observed that operation under repetitive fast voltage transitions is reducing reliability and lifetime of motor insulation due to the additional stress. Available data for allowable voltage pulse stress in insulation material is usually limited to voltage pulses having rise time below 300ns and dv/dt below several kV/us. With the introduction of wide bandgap power electronic devices, dv/dt will be significantly increased leaving the question about the impact on resulting insulation life time. In this paper insulation life time tests are presented under operating conditions similar to medium voltage SiC technology. Reversible and irreversible effects within the material are identified and their connection to switching speed and pulse voltage magnitude shown.

abstract: On May 1, 1988, when the ICE/V high speed experimental train of the German Federal Railways (DB) reached the world record speed of 406.9 km/h, it was the first time that the public at large was presented with the future train in high speed rail traffic. The electric traction equipment of such a forward looking means of traffic must logically represent the latest state of the art. Two development trends in particular characterize the technology. The first is the use of microprocessors for the complete control of the traction system and the second is the use of GTO thyristors for the converters. Siemens innovated the drive system taken from the class BR 120 locomotive of DB for the ICE/V by the development of a microcomputer traction control and a GTO converter. The microcomputer traction control is used for all 82 series power cars, the GTO converters will be provided for the second half of the series power cars.

abstract: Due to the increased switching speed and switching frequency of wide bandgap (WBG) device based power electronics, the common mode (CM) electromagnetic interference (EMI) noise issue has been exacerbated in the modern motor drive system. Understanding the high frequency impedance of an electric motor is critical in analyzing and mitigating the CM EMI issues. It is also essential to find the dominant parasitic capacitances within the electric machine, which serve as the primary motor to ground CM current paths. This paper investigates the impact of two different winding topologies, namely circumferential and toroidal windings, on the high frequency machine impedance. The geometry of two different windings is analyzed, and motor to ground capacitive coupling paths are identified. Two high frequency per phase motor impedance models are developed, and circuit parameters are extracted from the measured CM and differential mode motor impedance data. The influence of the high switching speed of SiC MOSFET on CM voltage is identified. The CM motor current is estimated under different switching speeds and different high frequency motor impedance models using simulation.

abstract: The field of electrical engineering is generally segmented into three major areas such that:electronics, power and control. Power electronics is a combination of these three areas. The advent of power semiconductor devices, thyristors in 1957, has been an exciting breakthrough in the art of electric power conversion and its control. In a modern power electronic equipment, there are essentially two types of semiconductor elements: the power semiconductors that can be considered as the muscle of the equipment, and the microelectronic control chips that provide the power to the brain. The DC motor are used extensively in adjustable speed drives and position control applications. Their speeds below base speed can be controlled by armature voltage control. Speeds above base speed are obtained by field flux control. As speed control methods for DC motors are simpler and less expensive than those for ac motors, dc motors are preferred wide speed control range is required. The dc motors used in conjunction with power electronic converters are dc separately excited motors or dc series motors. Depending upon the type of ac source or the method of voltage control, dc drives are classified as under: 1. Single phase dc drives 2. Three phase dc drives 3. Chopper drives.

abstract: This paper presents the power electronics advancement in electric traction drives. In this paper the power electronics traction transformer and multilevel converter are used to improve the performance of electric traction dives. In this paper power electronics devices are used with the traction drives so that the harmonics developed after inversion operation can be reduced using multilevel converter. The main advantage of multilevel converter kind of topology is that it can generate almost perfect current or voltage waveforms, because it is modulated by amplitude instead of pulse width.In this paper introduction to power supply used in electric traction and medium frequency transformers using cycloconverters are used to reduce the frequency of the AC supply used in electric traction. Combining modern high power semiconductor devices with constantly improving magnetic materials opens up the possibility to replace bulky low frequency transformers with a new medium voltage medium frequency conversion structure. This paper also discussed the power quality improvement in electric traction drives using power electronics devices. In this paper there is a discussion of the replacement of conventional pantographs by using unconventional current collection from a contact line for electric traction vehicles.
