This paper includes investigations of power losses in monolithic buck dc-dc converter designed with Cadence on CMOS 0.35 μm process. Input voltage of the designed circuit is equal to 3.6 V and output voltage is regulated to 1.2 V. Evaluated and estimated are power dissipations in the MOS transistor, filter inductor and filter capacitor of the buck converter. Investigated and compared are losses...

The stability and control of systems possessing passivity violations is considered. The authors seek to exploit the finite gain characteristics of a plant over a range in which a passive mapping no longer exists while implementing a similar hybrid passive and finite gain controller. Using the dissipative systems framework the authors define a hybrid system: one which possesses a passive map, an...

Abstract—The harmonic distortion of voltage is important in relation to power quality due to the interaction between the large diffusion of non-linear and time-varying single-phase and three-phase loads with power supply systems. However, harmonic distortion levels can be reduced by improving the design of polluting loads or by applying arrangements and adding filters. The application of passiv...

NB-PLC (narrowband power line communication) is a method of data communication that involves superimposing relatively high-frequency signal (9 kHz to 500 kHz), which contains data, onto the grid’s low frequency (50 60 Hz) signal. While using existing grid as transmission medium convenient, was not designed for this purpose, leading challenges such conducted emissions and infrastructure limitati...

We present the theory of modulation instability induced by spectrally dependent losses (optical filters) in passive driven nonlinear fiber ring resonators. Starting from an Ikeda map description propagation equation and boundary conditions, we derive a mean-field model---a generalized Lugiato-Lefever equation---which reproduces with great accuracy predictions map. The effects on gain comb gener...
