Switched reluctance motors (SRM) have many differences between traditional motors in performance analysis because of the special structure. First, the characteristics and structure parameters with large influence on the performance of SRM is discussed. Then a method for modeling and simulation of SRM system based on Maxwell and Simplorer is proposed. Finite element model of SRM with different structure...
A photovoltaic (PV) panel model is at the heart of an accurate performance model for a large PV farm. This paper presents an algorithm to calculate the parameters of the one-diode model of PV modules based solely on the manufacturer's datasheets. The important feature of this algorithm is that through reformulation of the characteristic equations at various points of the current-voltage (I-V) curve,...
Sneak circuit is studied widely since it is known in the early 1960s. Now it has become an important aspect of system reliability and security. And as more and more new topologies and characteristics are developed in the modern power system, the sneak circuit problem cannot be solved by using the conventional method. Petri net is powerful tool for describing and studying systems and it has been applied...
This paper introduces an improved transmission line NL-L (N ?? Z+, >2) de-embedding methodology by providing more stable and accurate transmission line characteristics, such as, Z0, phase and attenuation constants. More accurate results are achieved by using a deterministic matrix decomposition technique and also a more accurate ??-based circuit modeling of the parasitics for the probing pad adapters...
Sneak timing is an important aspect of sneak circuit. But now there are few researches on special sneak timing analysis in the sneak circuit analysis field. In this paper one method of sneak timing analysis in power system is studied. The systemic time interval which can be gained by the time Petri net model is used to describe the time characteristic of the system. The time Petri net of power system...
This paper presents a one-pin crystal oscillator realized in a standard 0.35-mum CMOS technology. Based on a three point oscillator topology, the single one-pin crystal oscillator core circuit is designed to operate over a supply voltage range of 1.62 V to 3.63 V, a temperature range from -10degC to 60degC in both fundamental and overtone modes. It allows a wide range of oscillation frequencies from...
