Board design simplified with cloud-based Wizard

In order to generate a list of possible DC/DC modules that would be acceptable for the current board design, the Wizard uses desired or required specifications set forth by the board designer. A variety of board parameters can be entered to help narrow the module selection, such as available input voltage, desired output voltage and current, maximum ambient temperature, minimum airflow and maximum allowable height. Once a list is compiled, modules are ranked by weighted user-selected preferences such as cost, density or efficiency. If preferred, the designer has the option to skip this stage and review the schematic generated from just the first level of requirements laid out.

Eliminating the need for multiple test and configuration tools, such as GE’s Tunable Loop Tool, Stability Tool, POL Programming Tool, Power Module Selector Tool or Power System Designer, the Wizard incorporates technology from each to provide a complete set of board design capabilities in a single, easy-to-use solution. In addition, the solution’s system design tool provides board designers with a variety of module combinations that specifically match the voltage needs of the application being designed.

Based on user specifications, the Power Module Wizard creates a schematic to show the complete circuit of the selected module and all connected external components. From this schematic, a set of four simulation tools (stability analysis, averaged load transient, switched load transient and ripple current and voltage) can be used to check the robustness of the design and the specified performance of the module. To optimize the solution, various external components throughout the schematic can be edited or reconfigured to enhance the design without having to restart the entire design process.

Once simulation results are within the desired range, a bill of materials with estimated pricing can be generated from the tool, providing the board designer with the necessary information he/she needs to start production of the application. In addition, a summary report with information on the specifications, parts selected and simulation results can be generated and exported in a PDF document, which can be shared among design team members, enabling simplified collaboration on the design and production of the board.

The tool can be accessed from any Web-connected computer, owing to the tool being cloud-based. It is available online and free of charge. Other tools require vendor approval or licensed installations of the application to operate on a designer’s computer. In addition to the online tool, an off line simulation-only version is available for locations with restricted web access.

“Previously, assorted board design and testing solutions needed to be individually downloaded and run separately by a designer,” commented Karim Wassef, general manager of the Embedded Products product line for GE’s Critical Power business. “Our new Power Module Wizard provides users with an innovative board design tool that integrates various design, optimization and testing capabilities into a user-friendly, cloud-based solution, empowering customers to make informative decisions on their DC/DC power solutions. It is among the first Web-based tools from a DC/DC module manufacturer to provide such a comprehensive set of rapid board design features.”
