摘 要 瞬態(tài)仿真領(lǐng)域的許多工作需要獲得可視化數(shù)據(jù), 仿真電路不能將輸出參數(shù)繪制成圖形時(shí)研究工作將受到很大影響. 而權(quán)威電路仿真軟件PSpice 在這個(gè)方面不盡如人意. 本文提出了一種有效的解決辦法: 通過(guò)MATLAB 編程搭建一個(gè)PSpice 與MATLAB 的數(shù)據(jù)接口,使PSpice輸出數(shù)據(jù)文件可以導(dǎo)入到MATLAB中繪制圖形. 這令我們能夠很方便地獲得數(shù)據(jù)的規(guī)律以有效地分析仿真結(jié)果, 這項(xiàng)技術(shù)對(duì)于教學(xué)和工程實(shí)踐都有比較實(shí)際的幫助.關(guān)鍵詞: 瞬態(tài)仿真 仿真程序 PSpice MATLAB 可視化數(shù)據(jù)The Data Transfer from Pspice to MATLABWu hao Ning yuanzhong Liang yingAbstract Many works in the area of TRANSIENT simulation has shown how a emulator such asPSpice can be interfaced to an control analysis package such as MATLAB to get viewdata. Thepaper describes how such interfaces can be made using the MATLAB programming.

Semiconductor memory, card readers, microprocessors,disc drives, piezoelectric devices and digitally based systemsfurnish TRANSIENT loads that a voltage regulator mustservice. Ideally, regulator output is invariant during a loadTRANSIENT. In practice, some variation is encountered andbecomes problematic if allowable operating voltage tolerancesare exceeded. This mandates testing the regulatorand its associated support components to verify desiredperformance under TRANSIENT loading conditions. Variousmethods are employable to generate TRANSIENT loads, allowingobservation of regulator response

Agilent 34401A Service Guide.pdfIEC Measurement Category II includes electrical devices connected to mains at an outlet on a branch circuit. Such devices include most small appliances, test equipment, and other devices that plug into a branch outlet or socket. The 34401A may be used to make measurements with the HI and LO inputs connected to mains in such devices, or to the branch outlet itself (up to 300 VAC). However, the 34401A may not be used with its HI and LO inputs connected to mains in permanently installed electrical devices such as the main circuit-breaker panel, sub-panel disconnect boxes, or permanently wired motors. Such devices and circuits are subject to overvoltages that may exceed the protection limits of the 34401A. Note: Voltages above 300 VAC may be measured only in circuits that are isolated from mains. However, TRANSIENT overvoltages are also present on circuits that are isolated from mains. The Agilent 34401A are designed to safely withstand occasional TRANSIENT overvoltages up to 2500 Vpk. Do not use this equipment to measure circuits where TRANSIENT overvoltages could exceed this level.
