This paper analyzes the influence of non-sinusoidal inductance distortion on saliency-based position estimation for permanent magnet (PM) machines. Because high-power-density design PM machines, flux saturation usually causes self-saturation, cross-saturation, and most importantly, secondary harmonics. fully investigates effect drives. Analytical model with saturated is developed to understand ...

for the purpose of modeling modern VRM, parasitics of VRM must be fully characterized. This paper presents experiment methods to characterize fast switching modern VRM. Results of parasitics, including inductance and resistance, of fast switching VRM are provided. Introduction Modern voltage regulator modules (VRM) for microprocessors have developed to a very high efficiency, very high current ...

This technical report presents the development of a simple envelope, or group, delay filter whose magnitude response emulates allpass characteristics for relatively broad frequency passbands. Unlike traditional allpass delay networks, the filter presented herewith exploits no inductances and maintains a common ground between its input and output ports. The absence of circuit inductances simplif...

A method is proposed to compute moments of distributed coupled RLC interconnects. Both uniform line models and non-uniform line models will be developed. Considering both self inductances and mutual inductances in multi-conductors, recursive moment computations formulae of lumped coupled RLC interconnects are extended to those of distributed coupled RLC interconnects. By using the moment comput...

In this paper we consider the Rapid Single-Flux Quantum (RSFQ) circuits with reduced Josephson current density and especially deal with one of the basic building blocks of these electronics the DC to SFQ converter. For future promising RSFQ applications the critical current of the Josephson junctions should be reduced (by reduction of Josephson current density) to several μA, resulting into val...
