The way in which electric power depends on the topology of circuits with mixed voltage and current sources is examined. The power flowing in any steady-state DC circuit is shown to depend on a minimal set of key variables called fundamental node voltages and fundamental edge currents. Every steady-state DC circuit can be decomposed into a voltage controlled subcircuit and a current controlled s...

This paper describes a new Bandgap Reference (BGR) architecture with low power consumption and high Power Supply Rejection Ratio (PSRR). Implemented in a 65nm CMOS technology, the circuit includes a pre-regulator, a current source and also digital validation for the bandgap voltage. The current consumption is below 4.9μA at 50oC, PSRR of -110dB@1kHz and -61.3dB@10MHz. The reference output volta...

In this paper three leg Voltage source converter (VSC) based Hybrid Active Power filter (HAPF) is proposed for existing problems of harmonics, reactive power compensation, high total harmonic distortion (THD) and Power factor improvement for three phase non linear loads. In the system, a hybrid active power filters which is the combination of active filter and passive filter. The reference curr...

In neuroelectrophysiology one records electric potentials or magnetic fields generated by ensembles of synchronously active neurons in response to externally presented stimuli. These evoked responses are often produced by multiple generators in the presence of ongoing background activity. While source localization techniques or current source density estimation are usually used to identify gene...

In recent years, there has been a fast growth in wind energy conversion system (WECS). There are two general types of wind turbines in WECS: fixed speed wind turbines and varying speed wind turbines.Permanent magnet synchronous generator (PMSG) is one of the most attractive generators for the varying speed turbine WECS.In this paper, a fuzzy controller is proposed to control the current source ...

In this paper, a novel stator current based Model Reference Adaptive System (MRAS) estimator for speed estimation in the speed-sensorless vector controlled induction motor drives is presented. In the proposed MRAS estimator, measured stator current of the induction motor is considered as a reference model. The estimated stator current is produced in an adjustable model to compare with the measu...
