The article presents a new method of counteracting shaft voltages and currents in AC electrical machines. It is based on the use an auxiliary winding located stator machine. design test stand adapted to measurement machine, prototype synchronous machine with permanent magnets, has been presented. model was used conduct number laboratory tests aimed at confirming functionality various operating ...

In this paper, we present an approach for applying two supply voltages to optimize power in CMOS digital circuits under the timing constraints. Given a technology-mapped network, we first analyze the power/delay model and the timing slack distribution in the network. Then a new strategy is developed for timing-constrained optimization issues by making full use of slacks. Based on this strategy,...

Increasing the short circuit current due to the penetration of distributed generations (DGs) in various voltage levels and meshed topology is a basic problem in power systems. Using fault current limiter (FCL) is an efficient approach to mitigate the exceeded short circuit levels. In this paper, a new approach is presented for multiple FCLs locating to decrease short circuit levels in meshed ne...

An intelligent strategy for the protection of AC microgrids is presented in this paper. This method was halving to an initial signal processing step and a machine learning-based forecasting step. The initial stage investigates currents and voltages with a window-based approach based on the dynamic decomposition method (DDM) and then involves the norms of the signals to the resultant DDM data. T...

A method to evaluate internal voltages through a builtin test structure is presented. Multiplexers are used to increase accessibility. The test structure does not affect normal operation of the circuit. Individual subcircuits can be tested selectivel,v based on evaiuated internal voltages.
