The Power IC Model Library incorporates over 200 time-domain simulation models for power electronic designs and gives designers capabilities previously unavailable for these popular parts - the ability to plug in a model, representative of the actual IC, and simulate the switching performance under actual operating conditions.
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.
The Power IC Model Library, a product of AEi Systems, is specially designed for the Cadence® PSpice® analog and mixed signal simulator. Nonlinear characteristics such as propagation delay, switching speed, drive capability and maximum duty cycle/current limits, 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, hysteric current control, low voltage, and low operating current.
The models utilize analog behavioral elements, 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.
- Analyze large signal effects like start-up transients, power stage semiconductor stress, and step-load response
- Explore different approaches to transformer, converter, filter, and control structures
- Compute component stresses and test for excessive power dissipation
- Compare circuit characteristics with linear and nonlinear magnetics
- Analyze in both time and frequency domains
- Simulate and analyze your entire power supply without ANY limitations.
The library includes example application circuits for most of the IC models. Symbols, model librarys and schematic sets are available for both Cadence OrCAD® Capture and Microsim Schematics. 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 stress analysis for all major components. In summary, you can simulate your entire power system.

Some newly added models in the Power IC Model Library for PSpice 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.
