Program Streamlines Power Converter Simulation
Mar 1, 2004
To meet the need for a simple Windows-based circuit-simulation program, a new software package called Power Circuits 101 is available for modeling electrical...

AC Rectifier Bulk Capacitor Selection with Analysis+SPICE
Nov 1, 2003
This exercise demonstrates how the blend of analysis + simulation/testing can lead to a better understanding of circuit performance, compared to using analysis or simulation/testing alone....

Test Diagnosis Software Verifies SMPS Design
Jul 1, 2003
Using the fault and test diagnosis software, a design can be fully tested for potential part failures....

Ultra-Fast Simulation Expedites Accurate SMPS Design
Mar 1, 2003
A designer can put together a complete design before ordering the parts needed to build a prototype by using merely a desktop computer and some innovative SPICE software....

SPICE Conducts EMI Analysis
Jan 1, 2003
When designing a switchmode power supply, the input EMI filter is often considered the most difficult part because simple means are missing to predict...

Lossy SPICE Models Produce Realistic Averaged Simulations
Jul 1, 2002
Standard averaged converter models do not include the losses. Instead, they usually insert ideal elements, and calculations omit some voltage drops....

CAD/CAE Software Aids Converter Design
Jul 1, 2002
Before the availability of computer-aided engineering software designed to run on PCs, engineers had little choice but to simplify assumptions for ballpark estimates of system performance. As a result, magnetic circuit analogies were used in place of true field analysis, and frequency response methods were used to evaluate stability in place of actual transient analysis....

In-Line Equations Describe Circuits in a Snapshot
Apr 1, 2002
Analog behavioral modelling allows designers to implement their own devices when only first order effects are necessary....

Sugar and SPICE: Determining Input Bulk Capacitor for Switchmode Power Supplies
Jan 1, 2002
This is the first of a series of regular columns with tips and tricks for using SPICE to aid in the design of switchmode power supplies....

SPICE Models Verify SMPS Designs
Jul 1, 2001
Generic SPICE models speed SMPS simulations....

Capacitor Characteristics Impact Power Supply Decoupling
May 1, 2001
Noise management, induced by digital circuits on a p. c. board assembly, deserves the attention of power supply designers and those mastering digital, analog, and mixed-mode application problems beyond the confines of the power supply itself....

Analyze IGBT Losses With Behavioral Models
Mar 1, 2001
Modern high speed insulated gate bipolar transistor (IGBT) applications in switchmode power supply (SMPS) circuits provide considerable cost, current...
