Power Supply Designer

Power Supply Designer combines the Power Deluxe version of the ICAP/4Windows analog and mixed-signal simulator with a powerful Magnetics Designer transformer and inductor synthesis tool. This is the industry’s only power-electronic design automation solution that furnishes a complete design entry, simulation and verification flow, including full magnetic synthesis, in one easy-to-use package. An intuitive graphical approach to all of applications makes its operation easy and fast. You can perform high-speed cycle-by-cycle simulation to show true large-signal performance of switching designs; simulate current-mode control using new state-of-the-art modeling techniques; run CCM and DCM converter simulations; analyze control systems, study open-loop design characteristics without breaking the closed loop; measure power stage loss; and activate component stress alarms to monitor power violation. Magnetics Designer designs and synthesizes all types of layer and section wound transformers and inductors, based on user prescribed electrical specifications. A winding sheet report and a SPICE-compatible model with parasitics are furnished as output. A database with thousands of cores, wide variety of materials and wire is included. In addition, you can add your own cores, wire and material information using a supplied Excel© spreadsheet. Several core vendors are supported, in addition to formvar, square or double square magnet wire, Litz wire, PCB traces and foil. Magnetics Designer calculates magnetizing and leakage inductance, inter-winding capacitance, peak flux density, DC winding resistance, high frequency AC resistance (including proximity effects and skin effect), copper loss (both AC and DC), core loss, weight, temperature rise, layer fill and window fill percentage. Typical applications include high frequency switching-regulator transformers; output chokes for off-line, full-wave and forward converters; 60 Hz single-phase line transformers; AC inductors; planar magnetic devices and 400 Hz aircraft transformers. Library elements run the course, featuring new hysteretic average models; General Feedback Theorem (GFT) models that preserve DC bias while measuring open loop properties; 30 power supply schematic templates with various ICs and custom power components for SMPS design; and a gamut of many other ready-to-use power devices, all totaling more than 22,700 parts. The package also provides SpiceMod, ICAP/4’s model building tool that easily creates and tests new models from manufacturers’ datasheet entry. And Library Manager organizes and archives models, including comparison and search capability. In all, Power Supply Designer designs, simulates and verifies your entire power system, or any analog, mixed-signal or mixed-systems design. Its schematic entry and design management system also includes footprint information for operation with the Bartels AutoEngineer PCB layout and route software.
