An Important Breakthrough For Power Engineers
“Many EDA vendors only have access to information in the data sheets, which is not sufficient when modeling a controller or regulator,” stated Charles Hymowitz, Managing Director of AEi Systems. “The data sheets simply do not have the level of detail required, and companies who rely solely on data sheet input produce substandard and inaccurate models.”
“AEi Systems has proprietary relationships with nearly all of the top analog IC manufacturers. Those relationships give AEi access to the part characteristics needed to produce models with the accuracy our customers expect,” stated Manny Marcano, President of EMA Design Automation. “Because AEi Systems is the sole developer of many Power IC models, this library contains parts that are not available from any other EDA company. At $995 per user, the library is a tremendous value, since single models can cost from $2,000 to $15,000 each to develop.”
Complex Models, Verified with Bench Data
SMPS applications today are much more demanding than ever. Today's designs require increases in power IC functionality, switching frequency, and system interaction. State space based models simply do not reveal many important nonlinear factors that influence these performance characteristics. The models in this new model library enable designers to perform high-speed, cycle-by-cycle simulations to show true large-signal performance, simulate current-mode control using the latest accurate modeling techniques, run CCM and DCM converter simulations, generate line and load step responses, and measure power stage loss and stress analysis for all major components.
The models in the Power IC Model Library are compared and verified with bench data under startup, steady state, line, and load transient conditions. Nonlinear characteristics such as propagation delay, switching speed, drive capability, maximum duty cycle/current limits, and startup phenomena are all accurately modeled. Designers can directly compare the performance of components from various vendors and analyze the effects of different implementations such as peak current mode control, hysteric current control, low voltage, and low operating current, to name just a few.
The Power IC Model Library for PSpice includes:
- Phase shift, voltage and current mode PWM controllers, switching regulators, motor controllers, power factor correction, power MOSFET drivers
- Popular parts: UC384x, UC152x, HIP2100, LT124x, UC182x, UC1846, TL431, IR2110, 57xxx, UC1854, TNY256, MIC44xx
- Nonlinear magnetic cores, transformers, opto-couplers
- Models for Texas Instruments, Intersil, ON Semiconductor, Linear Technology, National Semiconductor, International Rectifier, Micrel, Vishay, and more
