TL;DR: In this article, a multilevel topology using medium frequency transformers has been developed, which permits to reduce the weight and the size of the system and improves the global life cycle cost of the vehicle.
Abstract: With the new generation of full low floor passenger trains, the constraints of weight and size on the traction transformer are becoming stronger. The ultimate target weight for the transformer is 1 kg/kVA. The reliability and the efficiency are also becoming more important. To address these issues, a multilevel topology using medium frequency transformers has been developed. It permits to reduce the weight and the size of the system and improves the global life cycle cost of the vehicle. The proposed multilevel converter consists of sixteen bidirectional direct current converters (cycloconverters) connected in series to the catenary 15 kV, 16.7 Hz through a choke inductor. The cycloconverters are connected to sixteen medium frequency transformers (400 Hz) that are fed by sixteen four-quadrant converters connected in parallel to a 1.8 kV DC link with a 2f filter. The control, the command and the hardware of the prototype are described in detail.

TL;DR: Cascaded trans-Z-source inverters as mentioned in this paper use multiple magnetic cells in an alternately cascading pattern rather than a single magnetic cell with large turns ratio, which can produce the same highvoltage gain, while keeping currents and voltages of the components low.
Abstract: Inverters with high-output voltage gain usually face the problem of high-input current flowing through their components. The problem might further be exaggerated if the inverters use high-frequency magnetic devices like transformers or coupled inductors. Leakage inductances of these devices must strictly be small to prevent overvoltages caused by switching of their winding currents. To avoid these related problems, cascaded trans-Z-source inverters are proposed. They use multiple magnetic cells in an alternately cascading pattern rather than a single magnetic cell with large turns ratio. Simulation and experimental results have shown that the multicell inverters can produce the same high-voltage gain, while keeping currents and voltages of the components low. The inverters can also step down their output voltages like a traditional voltage-source inverter without compromising waveform quality.

01 Jul 1999TL;DR: In this article, an integrated planar inductor scheme for multi-module interleaved QSW power converters is proposed, which utilizes the phase relationships of the currents in each module to integrate all the separate inductors for each module into one core, resulting in great reductions in the size and power losses of the inductor.
Abstract: Compact, high-efficiency, low-voltage and large-current DC/DC power converters with a fast transient slew rate are needed for future generation microprocessors. The interleaved quasi-square-wave (QSW) topology is a good candidate to improve their transient response significantly. Inductors are critical components in these converters. An integrated planar inductor scheme for multi-module interleaved QSW power converters is proposed. This integrated inductor utilizes the phase relationships of the currents in each module to integrate all the separate inductors for each module into one core, resulting in great reductions in the size and power losses of the inductor.

25 Mar 2003TL;DR: In this article, a remote access device with a single form for the first, second and third inductors is proposed, where the first and second inductors are wound on the form.
Abstract: A remote access device which may comprise an antenna having a first inductor with a first axis, a second inductor with a second axis, and a third inductor with a third axis, where the first, second and third axes may be oriented substantially perpendicular to each other, respectively, such that the first inductor generates a first magnetic field associated with a first plane, the second inductor generates a second magnetic field associated with a second plane different than the first plane, and the third inductor generates a third magnetic field associated with a third plane different than the first and second planes. The remote access device preferably includes a single form for the first, second and third inductors, where the first, second and third inductors are each wound on the form.
