Area and Power Efficient Ultra-Wideband Transmitter Based on Active Inductor

Catherine Dehollain, Kerim Türe, Arnout Jan J Devos, Franco Maloberti

This paper presents the design of an impulse radio ultra-wideband (IR-UWB) transmitter for low-power, short-range, and high-data rate applications such as high density neural recording interfaces. The IR-UWB transmitter pulses are generated by modulating t ...

Leakage Flux Modeling of Multi-Winding Transformers for System-Level Simulations

Drazen Dujic, Min Luo, Jost Allmeling

In multiwinding transformers, different geometry of the individual windings leads to unbalanced leakage flux paths. The unbalance affects the behavior of the power electronic converters, where these transformers are used. This paper proposes an approach to ...

Discrete-Time Domain Modeling of Voltage Source Inverters in Standalone Applications: Enhancement of Regulators Performance by Means of Smith Predictor

Francisco Daniel Freijedo Fernández, Federico De Bosio

The decoupling of the capacitor voltage and inductor current has been shown to improve significantly the dynamic performance of voltage source inverters in standalone applications. However, the computation and pulse width modulation delays still limit the ...

Modelling Hysteresis of Soft Core Materials using Permeance-Capacitance Analogy for Transient Circuit Simulations

Drazen Dujic, Min Luo, Jost Allmeling

Magnetic components using soft core materials are widely used in power electronic converters. The hysteresis effect of the material leads to power loss and harmonic distortion. If this effect can be modelled in system-level time-domain simulation, the perf ...
