Small-signal modelling of the transistor laser including the quantum capture
and escape lifetimes



The transistor laser was rst introduced in , and it was
predicted that this device could have a high-speed modula-
tion bandwidth of up to 100 GHz . In the transistor laser
(TL), a quantum well (QW) is embedded in the base of the
bipolar junction transistor (BJT) and acts as an optical col-
lector. The stimulated recombination causes compression in
the I- ....etc

Power System Small-Signal Oscillation Stability
as Affected by Large-scale PV Penetration



W. Du, H. F. Wang, and R. Dunn



Abstract —

This paper investigates the impact of a large photovoltaic (PV) penetration on power system small signal oscillation stability. A comprehensive model of a single-machine infinite-bus power system integrated with a PV power generation power plant is established. Numerical computation of damping torque contribution from the PV power plant is carried out, wh ....etc

Abstract Test card for color TV is a widely used method to evaluate the quality of a TV set directly. We have made a test signal generator (which can also generate synchronizing (abbreviated to sync hereafter) signals) mainly based on microprocessor Z-80. Taking the advantage of microprocessor programming, combining with the technique of microprocessor, digital circuits and analogue devices, we use software as far as possible to generate signals directly or to simplify the controlling circuits. Those signals, such as composite sync signal, bla ....etc

INCREASING PENETRATION OF DISTRIBUTED
GENERATION IN EXISTING DISTRIBUTION
NETWORKS USING COORDINATED VOLTAGE

ABSTRACT
Connections of distributed generation (DG) to weak distribution networks often
experience voltage rise problems. The voltage rise caused by DG can be reduced
with passive methods such as increasing the conductor size but this can be quite
expensive. Active management of distribution networks can allow connection of
more DG into existing distribution networks and, consequently, reduce the connec-
tion ....etc

High frequency inverter design for large-signal characterization of domestic
induction heating load
Abstract –
Current research topics in the field of domesticinduction heating entail analytical study of inductor-potcoupling behavior which must be verified with experimentalresults. Small-signal measurements are easily achieved up to 1MHz with commercial LCR meters. On the other hand, largesignalexperimentation requires a custom made measurementtest bench. Whatever the approach selected to design thissystem, the ....etc

Design Of Power System Stabilizer To Improve Small Signal Stability By Using Modified Heffron-Phillip’s Model
Abstract:
One of the major problems in power system operation is related to small signal instability caused by insufficient damping in the system. The most effective way of countering this instability is to use auxiliary controllers called Power System Stabilizers, to produce additional damping in the system. Generally Heffron-phillip’s Model of a synchronous machine is commonly used for the small ....etc
