GE’s Power Module Wizard helps select best DC/DC power module

GE’s Critical Power business has launched its cloud-based Power Module Wizard uses desired or required specifications set forth by a board designer to generate a list of possible DC/DC modules for their current board design. Board designers can enter a variety of basic search parameters—such as available input voltage, desired output voltage and current, maximum ambient temperature, minimum airflow and maximum allowable height—to help narrow the module selection. 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.

The Power Module Wizard helps to eliminate the need for multiple test and configuration tools—such as GE’s Tunable Loop Tool, Stability Tool, Point of Load (POL) Programming Tool, Power Module Selector Tool and Power System Designer—by incorporating 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.


As a cloud-based solution, the Power Module Wizard enables designers to access the tool from any Web-connected computer. 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.

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.
