A newly devised inductance-oscillator (iOSC) has been developed which evaluates inductance impact on on-chip interconnect delay. iOSC is a ring oscillator which is comprised of a set of wires each with different loop inductance and accurate on-chip counter. The equivalent distance to the nearest ground grid, which serves as the current return path, is varied to control wire inductance. A test c...

Hardware complexity of a motor drive can be reduced by estimating controls rather than measuring using sensors. In this way the corresponding sensors are eliminated and the system becomes more robust. This article is about speed control of a sensor less induction motor with predictive current controller technique. This particular speed control technique does not require direct measurements of m...

A new approach to handle the inductance effect on multiple signal lines is presented. The worst case switching pattern is first identijied. Then a numerical approach is used to model the effective loop inductance (Leg) for multiple lines. Based on look-up table for Leg, an equivalent single line model can be generated to decouple a specific signal line from the others to per$orm static timing a...

On-chip inductance extraction and analysis is becoming increasing critical. Inductance extraction can be difficult, cumbersome and impractical on large designs as inductance depends on the current return path — which is typically unknown prior to extracting and simulating the circuit model. In this paper, we propose a new circuit element, K, to model inductance effects, at the same time being e...

The intermittent power generation of Distributed Generators (DGs) poses significant challenges to the operation grid. This intermittency, caused by variable nature renewable energy sources like solar and wind, leads flow imbalances voltage fluctuations. Consequently, a thorough analysis DGs integration, considering network contingencies, overloading concerns, thermal limits substations, is esse...

Wireless power transfer system is a modern technology which allows the transfer of electric power between the air-cored coils of its transformer via high frequency magnetic fields. However, due to its coil separation distance and misalignment, maximum power transfer is not guaranteed. Based on a more efficient and general model available in the literature, rederived mathematical models for eval...

The phase shift full bridge (PSFB) converter allows high efficiency power conversion at high frequencies through zero voltage switching (ZVS); the parasitic drain-to-source capacitance of the MOSFET is discharged by a resonant inductance before the switch is gated resulting in near zero turn-on switching losses. Typically, an extra inductance is added to the leakage inductance of a transformer ...
