Code Convertor-Binary to Uniform Minimal Switching Representation (UMSR)

2021 5th International Conference on Trends in Electronics and Informatics (ICOEI), 2021
The low-power arithmetic design has become a very important aspect for recent compact electronic gadgets. The need to minimize dynamic power dissipation is vital for combinational circuits. Switching activity is a vital reason for the dissipation of power in combinational circuits, which includes activities like spurious pulses, called glitches ...

Time-domain analysis methods for switching convertors

1988., IEEE International Symposium on Circuits and Systems, 2003
Two algorithms are presented for a time-domain analysis of a switching convertor which is replaceable with a piecewise-linear system. One of these algorithms is for the transient state analysis and the other is for the steady-state analysis. Both algorithms use eigenvalue and eigenvector calculations of the matrix.

Modified switched power convertor with zero ripple

Proceedings of the 32nd Midwest Symposium on Circuits and Systems, 2003
A modified power conversion scheme suitable for switched mode converters which addresses the problem of output ripple without incurring an appreciable loss of efficiency is presented. An analog controlled current source is used to inject a current into the load which is equal and opposite to the ripple current due to the switching circuit.

Power convertor circuits for switched reluctance motors with the minimum number of switches

IEE Proceedings B Electric Power Applications, 1990
The phase windings of a doubly salient switched reluctance motor are fed with unipolar pulses of current from a suitable power convertor to control the speed and torque of the motor. A new range of power convertor circuits for the switched reluctance motor is proposed in this paper.

Zero-voltage-switching three-phase single-stagepower factor correction convertor

IEE Proceedings - Electric Power Applications, 1997
As an alternative to two-stage cascaded AC/DC power convertors, the paper presents a zero-voltage-switching (ZVS) single-state three phase rectifier with input/output isolation. The proposed rectifier contains five active devices driven by a simple PWM controller and operates in the discontinuous conduction mode (DCM) for the input power factor ...

Fast Digital to Analog Convertor using Spatial Wave Switched FETs

International Journal of High Speed Electronics and Systems, 2014
In this paper, we are presenting fast digital to analog convertor designs using Spatial Waveform Switched FETs (SWSFET). SWSFET was introduced by Jain et.al. These FETs have multiple channels stacked vertically. The Carrier wavefunction switches from one channel to another with the application of different gate voltages.

Automated ripple analysis using KBM method [switching power convertor harmonics]

Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat. No.97CH36066), 2002
Conventional averaged models of switching power converters are useful for control loop design, but are inadequate for the main circuit design because of their inability to predict waveform details. A systematic method for recovering ripple components from the averaged model is presented in this paper.

Flexible capacitor and switch generators for automatic synthesis of data convertors

1991 IEEE International Symposium on Circuits and Systems (ISCAS), 1991
Two flexible and technology-independent module generators providing very compact and high performance realizations of binary weighted capacitor (BWC) and scaled switch (SS) arrays have been implemented. These generators are general enough to become a powerful tool in layout compilers for binary-weighted-capacitors-based analog-to-digital converters ...

Saturable reactor assisted soft-switching full-bridge DC-DC power convertors

IEE Proceedings B Electric Power Applications, 1991
A new soft-switching converter technique is introduced which employs small saturable reactors and phase-shift modulation. This considerably reduces switching losses with no substantial increase in conduction losses. The proposed soft-switching concept and its modifications to full-bridge DC-DC power convertors are shown and discussed.

Logarithmic and exponential switched-capacitor convertors and some of their applications

IEE Proceedings G (Electronic Circuits and Systems), 1988
The paper is devoted to the design of nonlinear analogue CMOS switched-capacitor (SC) circuits which realise logarithmic and/or exponential transfer characteristics. Some new circuit arrangements for SC logarithmic exponential convertors and exponential time-function generators are presented.
