4         Getting Start

4.1            Select topology at front page

Click on any topology window to select a topology

4.2            Select topology at other sub-page

You can click “Select topology” to go back to front page to select another topology

4.3            Add more outputs

Click the link “Add O/P” to add more output.

4.4            Changing input voltage and current

Enter the input voltage range Vin_Min - Vin_Max, output voltage Vo and rated current Io at each output.

4.5            First thing to do - Initialize Design

Once input and output are defined, press the button “Initialize Design.” A preliminary design will be recommended by PowerEsim.

4.6            Add Stack Winding

You can press “Add Stack” to add ac stack winding before and after the design initialized.

4.7            Select a part from schematic page

After design initialized, you can click on the component to go into the component selection user interface.

4.8            Component Selection User Interface – searched components box

1. Fill in the range of the searching criteria, and press “Search,” all the component fulfill the criteria will be displayed at the searched components box and ready to be chosen.
2. “Total Losses” will be shown for the converter using the highlighted component.
3. “Highlighted Losses” will be shown for the highlighted component.

4.9            Change a component from database

1. Select any one component from the searched components box
2. Click “Select One”
