Shooting Newton Steady-State Solver
The "Shooting Newton" Steady-State Solver enables you to:
- Achieve faster simulation time for power converter design
- Compute periodic steady-state solution directly
Available only with Keysight ADS: not in most SPICE-based circuit simulators
Power Electronics Model Builder (PEMB)
GaN Model extraction now available. Internal CurveDigitizer now available.
The PEMB:
- Enables the designer to build custom models for GaN, Si, SiC, and IGBT switching devices
- Builds models directly from digitizing the IV and CV curves from the vendor datasheet via an ADS built-in CurveDigiitzer
- Fits digitized data using the Artificial Neural Network (ANN) in the model creation process
Thermal Analysis
Keysight’s Advanced Design System (ADS) software continues the innovation that has made it the industry’s most trusted Power Electronics (PE) Electronic Design Automation (EDA) software tools. ADS for Power Electronics offers:
- Thermal Analysis Board-Level: Analyze hot spots on your PCB via a graphical heat map
- Thermal Analysis Schematic-Level: compute power losses and estimate junction temperatures on your schematic design
SMPS designers care about reliability of their products. In this video we will demonstrate how PEPro can now perform a thermal analysis to discover regions of failure, and reduce number of board spins.
Peak current-controlled buck regulator design used in EMI curriculum
Power Electronics EMI Curriculum Handbook
This new handbook provides hands-on learnings experience on the fundamentals of electromagnetic interference (EMI) in Power Electronics.
- Learn about EMI effects in a power converter design via 8 experiments
- Simulate using Keysight’s ADS and PEPro simulation software
- Validate with measurement using Keysight instruments
Switched-Mode Power Supply (SMPS) Performance Test Bench
The new SMPS Performance Test Bench:
- Enables designers to run a series of simulated tests, either in a schematic design environment for a schematic-only type simulation or in the PEPro environment for a post-layout type simulation which includes the layout parasitics
- Offers a transient recovery test and efficiency test which enable designers to gain insight into the behavior of designs under various loading conditions
