AEi Systems announces the
New Power IC Model Library
for PSpice® and OrCAD® -- Now Version 4.3!

AEi Systems is now selling the Power IC Model Library for US$1995.00**. This product is specially designed for the PSpice analog and mixed signal simulator. The Library has over 550 hyper-accurate cycle-by-cycle transient models that individually cost between $1000 - $14,000 EACH to develop, all in one convenient place.

The new 4.3 update includes

  • Automotive Stimulus Models (ISO 76750/FMC1278)
  • LISN Models
  • Opamp and Comparator models
  • Ferrite Beads
  • Regulators
  • Phototransistors and Photocouplers
  • MOVs

The Power IC Model Library for PSpice also includes:

  • Popular parts: UCC3895, xx117, UC384x, UC152x, UCC380x, LT124x, UC182x, UC1846, TL431, IR2110
  • Nonlinear Magnetic Cores, Transformers, Opto-Couplers and MOVs
  • BJTs, Diodes, Zeners, Varactors, Tantalum Capacitors, MOSFETs
  • Models for parts from Texas Instruments, Intersil, ON Semiconductor, Linear Technology, International Rectifier, Micrel, Vishay, and others
  • Ford EMC transient sources (CI 210, 220, 221, 222, 230, 231, 250, 260 and 280)

NEW - FORD EMC Transient Sources
The Power Library, starting with version 4.3, includes SPICE Models for FORD’s FMX1278 EMC Transient Test Sources. Stimulus generators are included for Immunity and ESD test CI 210, CI 220, CI 221, CI 222, CI 230, CI 231, CI 250, CI 260 and CI 280

Hard to Find Power IC Models
Texas Instruments, International Rectifier, Analog Devices, National Semiconductor, Vishay, Intersil, Power Integrations, Micrel, and ON Semiconductor, are just some of the vendors represented.

Pulse Width Modulation (PWM) controllers, Switching Regulators, Multi-phase controllers, PFCs, Integrated switch & boost controllers, hysteretic controllers, IC regulators, and models for other popular parts (FET drivers, opto-couplers, etc.) are included.

You can perform high-speed cycle-by-cycle simulation to show true large-signal performance, simulate current-mode control using the latest accurate modeling techniques; run CCM and DCM converter simulations; analyze control systems including loop gain, input filter design, and analysis; and measure power stage loss and perform stress analysis for all major components. In summary, you can simulate your entire power system.

PSpice in Version 16.x provides speed increases for complex power supply simulations
Some of the Power IC Model Library for PSpice’s newly-added models incorporate recent PSpice built-in component and building block advances -- advances that allow models to take full advantage of PSpice’s capabilities. The new version of PSpice also includes speed increases for simulation of math equations and “if-then-else” constructs that are used throughout the model library. This improvement results in speed increases of 10 to 40% for power supply simulations.

A Major Breakthrough
SMPS applications today are much more demanding than ever. Today's designs require increases in switching frequency, higher efficiency, and lower standby current. State space based models simply do not reveal many important nonlinear factors that influence these performance characteristics.

Nonlinear characteristics such as propagation delay, switching speed, drive capability, maximum duty cycle/current limits, and Startup phenomena are all accurately modeled. You can directly compare the performance of components from different vendors and analyze the effects of different implementations such as peak current mode control, hysteretic current control, low voltage, and low operating current, to name just a few.

The models utilize analog behavioral elements and special Boolean logic elements. Together they greatly reduce the model’s simulation runtime, an important factor in SMPS analysis. Most simulations run in just a few minutes.

The library includes example application circuits for most of the IC models. Symbols, libraries, and schematic sets are available for both MicroSim Schematics as well as OrCAD Capture.
