This paper deals with simulation of shunt active filters using fuzzy logic to improve the power quality and reduction in the transient time of capacitor voltage, when there is change in load. Shunt active power filter can compensate current harmonics by injecting equal-but-opposite harmonic compensating current .A new control strategy is proposed which is based on energy of the capacitor, dc-li...

Comparator based switched capacitor circuits provide an excellent opportunity to design sampled data systems where the virtual ground condition is detected rather than being continuously forced with negative feedback in Opamp based circuits. This work is an application of this concept to design a 1 order 330 KHz cutoff frequency Lowpass filter operating at 10 MHz sampling frequency in 0.13μm te...

Recent years, embedded generators have been increasingly installed in distribution system in many parts of the world. Depending on their operating characteristics and locations, embedded generators could significantly affect the voltage profile, network losses and fault level in a distribution system. This paper presents a new technique for determining optimal allocation and sizing of embedded ...

The paper describes a case study of new 12-bit low power switched-capacitor (SC) ADC for portable applications. The paper is focused on block design of ADC and its behavioural modelling regarding low power consumption. It is reached by Op-Amp sharing technique utilisation. The basic block topology design is outlined too. The cancellation techniques for avoiding of capacitor mismatch, clock feed...
