An Effective Nontransient Active Short-Circuit Method for PMSM in Electric Vehicles

IEEE transactions on industrial electronics (1982. Print), 2023
This article proposes an effective stepwise nontransient method for entering and exiting the active short circuit (ASC) of permanent magnet synchronous motor (PMSM) to protect the safety of vehicle's drive system when fatal faults occur in the electric ...

Two-Mode Active Balancing Circuit Based on Switched-Capacitor and Three-Resonant-State LC Units for Series-Connected Cell Strings

IEEE transactions on industrial electronics (1982. Print), 2022
This article proposes a two-mode active balancing circuit for series-connected cell strings. The proposed balancing circuit has two operation modes: any cell to any cell (AC2AC) and direct cell to cell (DC2C) modes.

Imaging activity in integrated circuits

2014 IEEE International Conference on Image Processing (ICIP), 2014
The need to detect and localize activity exists in a variety of fields and has broad applications ranging from brain activity for neuroscience to image/video change detection for scene surveillance. In this paper, we introduce a method for localizing activity in integrated circuits (IC) using a laser scanning microscope.

Generation of active inductor circuits

Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010
This paper proposes a novel systematic method of generating active inductor circuits. It is a graph-based approach that consists of building a flow-graph of a structure without inductors, whose transfer function is equivalent to the impedance or the admittance of an inductor, and then generating the equivalent circuit with only RC-elements, controlled ...

An analgesia circuit activated by cannabinoids

Nature, 1998
Although many anecdotal reports indicate that marijuana and its active constituent, delta-9-tetrahydrocannabinol (delta-9-THC), may reduce pain sensation, studies of humans have produced inconsistent results. In animal studies, the apparent pain-suppressing effects of delta-9-THC and other cannabinoid drugs are confounded by motor deficits.

Estimating circuit activity in combinational CMOS digital circuits

IEEE Design & Test of Computers, 2000
Largely because of the recent trend toward portable computing and wireless communication systems, estimating power consumption has become a major concern in today's VLSI circuit and system design. Moreover, the dramatic decrease in feature size, combined with the corresponding increase in the number of devices on a chip, makes the power density larger.

Complement Activation in Extracorporeal Circuits

Annals of the New York Academy of Sciences, 1987
Clinical studies performed with various types of hemodialyzers provide a data base and conceptual framework for understanding blood-material interactions that result in complement activation. Current findings suggest that the complement-activating potential of biomaterials may be defined by quantitating either fluid-phase C3a antigen or measurement of ...

AC–DC LED Driver With an Additional Active Rectifier and a Unidirectional Auxiliary Circuit for AC Power Ripple Isolation

IEEE transactions on power electronics, 2019
Single-phase ac light-emitting diode (LED) lamps require long-lifespan and high-efficiency ac–dc power converters for power factor correction (PFC) and current regulation.
