Opis:: This paper addresses the state-variable stabilising control of the power system using such series FACTS devices as TCPAR installed in the tie-line connecting control areas in an interconnected power system. This stabilising control is activated in the transient state and is supplementary with respect to the main steady-state control designed for power flow regulation. Stabilising control laws, proposed in this paper, have been derived for a linear multi-machine system model using direct Lyapunov method with the aim to maximise the rate of energy dissipation during power swings and therefore maximisation their damping. The proposed control strategy is executed by a multi-loop controller with frequency deviations in all control areas used as the input signals. Validity of the proposed state-variable control has been confirmed by modal analysis and by computer simulation for a multi-machine test system.

Tytuł:: Fast Low Voltage Analog Four-Quadrant Multipliers Based on CMOS Inverters

Opis:: The paper presents quarter-square analog four-quadrant multipliers, based on proprietary architecture using four CMOS inverters. The most important upgrade on already published own circuit implementation is the use of the same inverter "core" of the circuit with completely redesigned auxiliary and steering blocks. Two variants of new driving peripherals are considered: one with differential pair, the second with CMOS inverters. The proposed circuit solutions are suitable for RF applications in communication systems due to simple architecture comprising building blocks with RF CMOS transistors having sufficiently large biasing currents. Postlayout simulation results done on the basis of 180nm CMOS UMC Foundry Design Kit are also presented.
