Adaptive systems of traction power supply

Russian Electrical Engineering, 2014
At present, a great variety of traction power supply systems (TPSSs) are being used, planned, and developed for the future. This is because of the specifics of the electric transport system, as well as scientific and technological progress. The variety of TPSSs became possible as a result of the development of power semiconductors for transforming ...

Adaptive control of uninterruptible power supply based on AC/AC Power Converter

2014 International Conference on Multimedia Computing and Systems (ICMCS), 2014
This work deals with the problems of uninterruptible power supplies “UPS” based on the converter AC/AC built in two stages: an input stage AC/DC and an output stage DC/AC. The two blocks are joined by a continuous intermediate bus, such as power factor correction “PFC”, regulating the DC bus voltage and generating a sinusoidal output voltage.

Low-power CMOS digital design with dual embedded adaptive power supplies

IEEE Journal of Solid-State Circuits, 2000
A low-power CMOS design methodology with dual embedded adaptive power supplies is presented. A variable supply-voltage scheme for dual power supplies, namely, the dual-VS scheme, is presented. It is found that the lower supply voltage should be set at 0.7 of the higher supply voltage to minimize chip power dissipation.

Adaptive On-Chip Power Supply With Robust One-Cycle Control Technique

IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2006
In this paper, an integrated adaptive output switching converter is proposed. The design uses a one-cycle control for fast line regulation and a single outer loop for load regulation and fine tuning. A switched-capacitor integrator is introduced in the one-cycle control to obtain positive integration with a single positive power supply, allowing a ...

Adaptive Neuro-Wavelet Control for Switching Power Supplies

IEEE Transactions on Power Electronics, 2007
The switching power supplies can convert one level of electrical voltage into another level by switching action. They are very popular because of their high efficiency and small size. This paper proposes an adaptive neuro-wavelet (ANW) control system for the switching power supplies. In the ANW control system, a neural controller is the main controller
