WALKER, J. M. AND W. C. DIXON. A solid state device for measuring sensitivity to thermal pain. PHYSIOL BEHAV 30(3) 481-483, 1983.--A simple and inexpensive circuit for use in conducting the tail-flick test is described. The use of digital integrated circuits coupled to a thyristor phase control circuit holds the number of parts needed to minimum. Methods for the use of the device and statistica...

This paper Describes the design and simulate a single phase AC chopper module using IGBT as a power switch and designing and implementing the control circuit used to trigger the power switches. In this paper given that the difference between thyristor and IGBT. The reason for phase delay between main and freewheeling IGBT. In this paper control circuit is designed such that more related to the ...

This paper presents the use of Self Adaptive Firefly Algorithm to identify the optimal placement of Thyristor Controlled Series Compensator (TCSC) in a power system network. The objective is to minimise the transmission loss in power system network with the placement of TCSC. To validate the proposed algorithm, simulations are performed on three IEEE test system using MATLAB software package. S...

The model of interconnected numerical device segments can give a prediction on the dynamic performance of large area full wafer devices such as the GCTs and can be used as an optimization tool for designing GCTs. In this paper we evaluate the relative importance of the shallow p-base thickness, its peak concentration, the depth of the p-base and the buffer peak concentration.

The single-phase-to-ground (SPG) fault at the valve side of converter transformer is one most critical faults threatening operation bipolar half-bridge modular-multilevel-converter-based multi-terminal direct-current (HB-MMC MTDC) systems. Following a valve-side SPG fault, upper-arm submodule (SM) capacitors in faulty may suffer serious overvoltage, and grid-side currents experience no zero-cro...

Aircraft operate in diierent modes during ight, corresponding to diierent ight conditions and control schemes. We use diierential atness of an approximate model of the pitch dynamics of a thrust vectored aircraft to achieve fast switching between those modes. We investigate some methods to compensate for the perturbations to atness. Simulations and experimental data are provided to validate the...

Addressing power quality issues in shipboard microgrids (SMs), which are mainly attributable to the increased installation of converters, has received much attention recently. To this end, static VAR compensators, such as thyristor-switched capacitors and fixed capacitors-thyristor controlled reactors (FCs-TCRs), can be effective solutions. Controlling these however, is not a trivial task it in...
