  1. The Power of SABER Simulation Tools for Power Design Steve Chwirka Compel2000 Compel2000

  2. Introduction • Simulation Requirements for Power Systems • Robust Engine for non-linear, multiple feedback systems • Several levels of models - • Ideal to physic based detailed devices, signal flow control models • Average models to detatiled PWM IC models • Non-Linear magnetic models • DSP • Mechanical models (motors, alternators, generators) • Thermal modeling • Schematic capture, Post Processing • Analyses • Modeling language (mixed signal, mixed technology) • Comprehensive Library of existing models • Links to critical tools (FEA) Compel2000

  3. Schematic Capture & Analyses • Saber Sketch + • Input to Simulation • Analysis control • Waveform display • Hierarchical • Information • parameters, model • Report generation • Analyses • DC, DCT, Sensitivity • TR, AC • Distortion, noise • pole-zero, vary, FFT • Stress, Statistical, etc Compel2000
